BACKGROUND INFORMATION

General Statement of Problem

With the ever increasing number of consumer choices for television viewing, it is important for advertisers, content producers, and service providers such as cable television and satellite television and internet protocol television companies to be able to accurately measure audience reach at the house-level for various demographic groups within a geographic area where the house-level viewing accounts for various multiple devices in the home where those devices may or may not be viewing the same content at the same moment in time. Additionally, there is an urgent industry need to measure house-level viewing across all the devices in the home by demographic group for video programming across all channels and all minutes of the day.

Traditional methods of measuring television viewership do not provide one-second level viewing information aggregated to the house-level for various demographic groups even though this could be extremely helpful to advertisers, content producers, and content providers.

Advertising Industry Problem

Producing television ads and purchasing ad time to run those ads is expensive. Ideally, the advertising purchased with those dollars can be correlated with ad impressions. Unfortunately, measuring ad impressions or ad viewership is very difficult, especially when there are hundreds of channels and many of them are lightly viewed. The problem is magnified by channel-surfing and by multi-screen activity wherein one person may use personal viewing devices, traditional cable or satellite television, and perhaps computer based viewing. While traditional survey techniques provide audience measures for popular channels, they are inadequate for lightly-viewed channels, which can be up to 80% of the channels. In today's competitive media environment, television advertisers need accurate and detailed viewing information for video content aggregated to the house-level with suitable breakouts for demographic and geographic groupings so that they can measure the effectiveness of their advertising.

Advertisers need detailed house-level reach information on viewing of the ads that they pay to air. When an advertising campaign includes commercials that are aired on multiple programs at various times, and when a home has multiple viewing devices on which a viewer may be exposed to those ads, sometimes having the same ad on the same device at the same time, it is very important for an advertiser to be able to accurately measure house-level exposure to the ad. Additionally, the advertiser needs to know what demographic group in a particular geographic area was exposed to the ad. All of this information enables advertisers to make wise decisions regarding ad placement.

In order to be able to reach particular demographic groups, advertisers also need to know about the demographic characteristics of the audience that views any particular program. They need access to this information at minute-level, thirty-minute level, and sixty-minute level for all programs on all channels across all hours of the day.

I have not found any patents or patent applications that teach how to use set top box data to efficiently analyze second-by-second viewership of advertising to produce the detailed information that advertisers need.

Television Network Problem

Television networks need to create an appealing programming schedule with content that the viewers are interested in viewing. It is difficult for television networks to get accurate audience feedback, particularly for lightly viewed networks. They need to be able to measure demographic-based viewing patterns for each show. Traditional measurement tools do not provide the detailed information needed to help television networks understand how viewers are responding to the content. The result is that television networks may develop programming schedules that do not appeal to the audience. This is wasteful.

Content Producers Problem

Producing television content is often expensive. It is difficult for the content producers to get accurate audience feedback. Additionally, there is not one audience, but many audiences, because of the wide variety of viewer interests. Furthermore, various demographic groups may have different viewing preferences. The content producers need to tailor the content to the audience; understanding viewing based on demographic patterns is very helpful for this. With the increasing number of viewing choices it is all the more important to be able to accurately measure viewership of demographic groups. By identifying specific demographic groups and the content they prefer to consume, content producers can increase ad revenue by enabling advertisers to target ads based on the demographic characteristics of the audience thus justifying higher advertising fees. Traditional measurement tools do not provide the detailed information needed to help producers and writers to understand how viewers are responding to the content. The result is that producers may develop content that lacks interest to the audience. This is wasteful.

Cable Television Industry Problem

In the cable television industry, content providers offer consumers hundreds of channels. Cable television companies pay very large amounts of money for content. It is imperative for the cable television companies to be able to accurately measure audience viewership in order to understand what value the various programs bring to their customers. They must understand viewership by demographic groupings. Also, by understanding the time of day when various programs are viewed by the demographic groups, the cable television companies can create more attractive viewing schedules for their customers. Additionally, as cable television companies are able to accurately measure audience viewership, they will be able to better negotiate with the program providers on the price to be paid for programming content and with advertisers on the price to charge for airing advertising.

Satellite Television Industry Problem

The satellite television industry faces the same problems as the cable television industry in regard to understanding what programming the viewers are watching and at what time of day and on what device. In general they have the same need to understand viewer behavior as do the cable television companies.

Internet Protocol Television Industry Problem

The Internet Protocol television (IP TV) industry faces the same problems as the cable television industry in regard to understanding what programming the viewers are watching and at what time of day and on what device. In general they have the same need to understand viewer behavior as do the cable television companies.

Need for Information about the Customer

In addition to these issues, cable television companies, satellite television companies, IP TV providers, television content providers, television advertisers, and other interested parties are continually desiring to know more about the customers they serve, the patterns of customer interactions, the content customers find interesting or that keeps their attention, the ads they view, the time of day when various program are viewed, how programs compare with one another in keeping viewer interest, and numerous other measures, all of which often vary by demographic group. With the advent of multiple video viewing devices in the home, the need to understand viewer behavior is even more important.

Fortunately, currently available technology enables the collection of raw data that, with proper analysis, can begin to answer many of these questions, and even do so with great specificity.

We will now look at some sources of raw data in the television industry.

Video Viewing Activity Data Sources

Since my original United States patent application having application Ser. No. 12/981,301 filed on Dec. 29, 2010, the industry has continued to mature. In the past it was common to refer to this data as Channel Tuning activity. While that term is accurate, in this specification I will often use the more general term Video Viewing Activity.

Within the video viewing space there are collection systems in place for collecting Video Viewing Activity. Such collection systems include switched digital video collection systems, set top box data collection systems, IP Television collection systems, EBIF agents, etc. Many such applications are now well established in the industry; others are continually being developed. Such data collection is beyond the scope of this patent application. It will suffice to know that the needed video viewing activity is available. Such Video Viewing Activity can readily be enriched to include demographic information about the house or about the viewer using the video viewing device. Such Video Viewing Activity can also be enriched to include Geographic information identifying where the viewing activity occurred.

Raw Video Viewing Event Data

This specification assumes that viewer interaction data can be delivered in a format that allows my Preprocessing Engine 140 and House Demographic Measurement Engine 200 to ingest it. I will refer to this format as Raw Video Viewing Event data. This can be provided from a Media Measurement Data Model (MMDM) or from some other data source. Once data is available in the Raw Video Viewing Event format, it can be readily processed using algorithms which I will teach about in this specification. The teachings of this specification are not limited to or dependent upon using data from a Media Measurement Data Model; that is simply one possible manner in which data may be provided. Data may also be provided in a simple flat file format or any number of other formats.

Processes for providing Raw Video Viewing Event data are beyond the scope of this patent application. Those skilled in the art will recognize that there are any number of methods that may be used to create the input files which my Measurement Engine 200 will use.

Video Program Schedule Data Sources

As with the collection of video viewing activity data, the availability of program schedule data is rapidly expanding. There are various industry standards in this area and new standards are being developed. For purposes of media measurement, these systems can provide the detailed information about the video programs, program schedules identifying when they aired in the various markets. This schedule information can be mapped in a user interface against the one-minute, thirty-minute, and sixty-minute aggregations which I teach how to create with the result that the end-user is able to correlate program schedule data with viewing activity. This correlation is beyond the scope of this teaching.

Advertising Schedule Data Sources

There are various advertising systems in existence today. For purposes of this specification, it is sufficient to recognize that data can be made available to identify the advertisements which are to be measured to determine ad reach.

File Transfer to Receive the Data

The Raw Video Viewing Event data can be made available to my Measurement Engine whether through SQL queries, data base extracts, XML messages, or any other computer readable format.

Encryption may be applied for data security purposes. Compression may be applied to reduce data transfer volumes.

Additionally, once the data is enriched, key identifiers can be hashed or encrypted or de-identified to protect the identity of the viewer.

Existing Tools for Data Analysis

We have seen by way of background that video viewing activity data and program schedule data is readily available. Regarding tools for using this data to analyze detailed viewing patterns, I am not aware of any vendor solutions or patents that load second-by-second channel tuning data or video asset viewing device usage data into a Data Structure in the memory of a computer to identify second-by-second video viewing activity and then filtering out duplicate viewing activity at a household level. I am also not aware of any such process that calculates advertising Reach at the household-level. I am also not aware of any such process that calculates advertising Reach at the household-level by demographic group. Finally, I am not aware of any process that calculates household level viewing data across all channels and all minutes of the day with viewing breakouts by demographic group.

Relevant Patents

The patents and patent applications identified below are only mildly relevant. I include them here to acknowledge that others have taught about using set-top box data, but none have used it as I teach in this application and none have been able to produce the detailed metrics that I have identified herein.

Examples include:

Conkwright, et al. in U.S. Pat. No. 7,383,243 issued Jun. 3, 2008 teaches about collecting set-top box data for the purpose of predicting what consumers will do, not for the purpose of understanding actual viewer behavior. It appears that he does not teach the loading of a data structure containing buckets representing individual units of time to analyze viewing behavior.

Hendricks, et al. in U.S. Pat. No. 7,590,993 Method and apparatus for gathering programs watched data issued Sep. 15, 2009 teaches about collecting tuning data from the set-top box and combining that with other data in a data base to determine the types of programming the STB tunes to. It appears that he does not teach the loading of a data structure containing buckets representing individual units of time to analyze viewing behavior.

Relevant Patent Applications

Wood; Catherine Alexandra in U.S. Patent Application 20070074258 dated Mar. 29, 2007 teaches about collecting subscriber activity data, such as channel changes generated by the subscriber while watching video or TV in an IPTV system. It appears that she does not teach the loading of a data structure containing buckets representing individual units of time to analyze viewing behavior. It appears instead that she teaches loading the channel tuning data to a relational data base and then performing various SQL based queries against that data base.

Eldering; Charles A.; et al. in U.S. Patent Application 20080127252 dated May 29, 2008 teaches about targeted advertising. He notes that SDV systems have the ability to provide viewership counts. It appears that he does not teach the loading of a data structure containing buckets representing individual units of time to analyze viewing behavior.

Allegrezza; Fred J.; et al. in U.S. Patent Application 20090077577 dated Mar. 19, 2009 teaches about aggregating information obtained from the messages to generate channel viewership information identifying a number of subscribers tuned to each broadcast channel over a period of time, but it appears to be based simply on tune-in activity. It appears that he does not teach the loading of a data structure containing buckets representing individual units of time to analyze viewing behavior.

Bou-Abboud; Claude H. in U.S. Patent Application 20070214483 dated Sep. 13, 2007 teach about a tool for predicting capacity demands on an electronic system. It appears that they do not teach the loading of a data structure containing buckets representing individual units of time to analyze viewing behavior.

Canning; Brian P.; et al. in U.S. Patent Application 20100145791 dated Jun. 10, 2010 teach about storing data in multiple shards and supporting queries against the data. It appears that he does not teach the loading of a data structure containing buckets representing individual units of time to analyze viewing behavior.

Summary of Short-Comings in Data Analysis Tools

In general, these methods do not suggest the concepts taught about in my application. They do not teach about calculating household reach; they do not teach about calculating household reach along with demographic breakouts; they do not teach about loading viewing activity to a data structure containing buckets representing individual units of time to analyze viewing behavior.

In general, a short-coming of the methods identified above is that the foundation is a non-procedural language (SQL) used in conjunction with a relational data base which together do not have the detailed processing capability required to perform complex analytics. In such an environment, in order to capture the richness of certain aspects of the channel tuning data, one would have to explode the data out into individual rows with one row for each second of viewer activity. In such an environment, this is extremely expensive because adding a primary key to each data record simply to record the second (time) multiplies the volume of data many times over because the size of the primary key requires much more storage space than the data being recorded. Thus we see that using a non-procedural language (SQL) in conjunction with a relational data base is very inefficient and requires extremely powerful data base servers to analyze this data. In contrast I am able to produce these complex analytics on a simple personal computer.

As a result of not being able to perform the detailed analytics required, the behavioral and device usage information contained in the data remains hidden from interested parties.

SUMMARY

In accordance with one embodiment, I have disclosed a computer-implemented method of using video viewer interaction data as input to a measurement engine which then calculates: demographic level and aggregate level (a) household reach for advertisements and video content based on user defined reach periods, (b) One-minute, Thirty-minute, and Sixty-minute channel viewing metrics, and (c) One-minute, Thirty-minute, and Sixty-minute aggregate viewing metrics, all based on second-by-second household level viewing activity. My teaching also shows creation of Commercial Schedule Cumulative Audience, Impressions for Reach Periods, Demographic Group Impressions, Average Audience, Average Audience Share, Average Rating, Households Using Television, and Households Using Television Percent using household level data. My method works with IP and linear video delivery. Together these metrics provide detailed information on customer viewing behavior which can be used to drive business decisions for service providers, advertisers, and content producers.

ADVANTAGES

By mapping the Video Viewing Activity with demographic identifiers to Aggregation Channels and then aggregating the viewing activity to those Aggregation channels at a house level and then using that aggregated data to calculate house-level reach, I am able to determine house-level reach for both advertisements and video content in aggregate and by Demographic group. Additionally, I am able to summarize the data that has been aggregated to the house-level within demographic groupings to create one-minute, thirty-minute, and sixty-minute aggregations across all channels and all minutes of the day with viewing breakouts by demographic group within a geographic area. Each of these are provide detailed viewing metrics that could not be produced previously. Existing analysis techniques simply do not allow the creation of the detailed viewing metrics which I have been able to produce. These metrics will allow service providers, advertisers, and content producers to make intelligent business decisions benefiting both themselves and their customers.

Comparison to My Prior Applications

In my co-pending United States patent application having application Ser. No. 12/981,301 filed on Dec. 29, 2010 entitled “SYSTEM AND METHOD FOR ANALYZING HUMAN INTERACTION WITH ELECTRONIC DEVICES THAT ACCESS A COMPUTER SYSTEM THROUGH A NETWORK”, which is incorporated in its entirety but is not admitted to be prior art, and in my co-pending United States patent application having application Ser. No. 13/052,026 filed on Mar. 18, 2011 entitled “SYSTEM AND METHOD FOR MEASURING TELEVISION ADVERTISING AND PROGRAM VIEWING AT A SECOND-BY-SECOND LEVEL AND FOR MEASURING EFFECTIVENESS OF TARGETED ADVERTISING”, which is incorporated in its entirety but is not admitted to be prior art, I taught populating a Data Structure with identifying information and device usage information such as channel tuning data to create a foundation upon which a comprehensive set of metrics can be produced. In those applications I also taught loading the tuning data on a second-by-second basis into buckets in a data structure for analytics.

In my co-pending United States patent application having application Ser. No. 13/360,704 filed on Jan. 28, 2012 entitled “SYSTEM AND METHOD FOR MEASURING LONGITUDINAL VIDEO ASSET VIEWING AT A SECOND-BY-SECOND LEVEL TO UNDERSTAND BEHAVIOR OF VIEWERS AS THEY INTERACT WITH VIDEO ASSET VIEWING DEVICES THAT ACCESS A COMPUTER SYSTEM THROUGH A NETWORK”, which is incorporated in its entirety but is not admitted to be prior art, I taught populating a Data Structure with identifying information and device usage information such as channel tuning data to create a foundation upon which a comprehensive set of metrics can be produced. In that applications I taught loading the tuning data on a second-by-second basis into buckets in a data structure and populating the buckets with a channel call sign to indicate viewing of the channel during that second; I then used this as a basis for creating analytics.

In my co-pending United States patent application having application Ser. No. 13/567,073 filed on Aug. 5, 2012 entitled “SYSTEM AND METHOD FOR MEASURING LINEAR, DVR, AND VOD VIDEO PROGRAM VIEWING AT A SECOND-BY-SECOND LEVEL TO UNDERSTAND BEHAVIOR OF VIEWERS AS THEY INTERACT WITH VIDEO ASSET VIEWING DEVICES DELIVERING CONTENT THROUGH A NETWORK” by the present inventor which is incorporated by reference in its entirety but is not admitted to be prior art, I taught populating a Data Structure with identifying information including video program being viewed, a video program airing being viewed, and fields to identify the demographic, geographic, and device information related to the viewer and the viewing device he is using to create a foundation upon which a comprehensive set of metrics can be produced. In that applications I taught loading the tuning data on a second-by-second basis into buckets in a data structure and populating the buckets with various Activity Fields including (a) an identifier to indicate the activity of the user during that second with activity being things such as Play, Skip, Forward (at various speeds), Reverse (at various speeds), etc., (b) volume level, (c) foreground/background indicator, (d) percent content visible, (e) picture in picture indicator, (f) a percentage of screen this video, and (g) a viewer interaction score which assigns a value to the viewing activity that was occurring on a second-by-second basis; I then used this as a basis for creating analytics.

Advantages of this Application

In this House Demographic Viewing Specification, I teach populating a Channel Viewing Detail One-Second Array Data Structure FIG. 14 with information identifying geographic, demographic, channel, and house values along with buckets for each second of the day where the bucket is used to identify viewing activity of that channel in that house during that second of the day. The data structure links the house with the geographic and demographic values. By aggregating the data at the channel+house level this Measurement Engine is able to filter out multiple devices in or associated with the same house and all viewing the same content at the same time, thus providing the basis for accurate house-level audience reach calculations.

The reader will recognize that in each of the several embodiments from the current and prior applications, I teach loading values that identify second-by-second video program viewing activity to selected buckets in a viewing detail data structure based on the beginning and ending time of the user interaction, thus identifying second-by-second video program viewing activity showing whether or not the video asset viewing device was viewing or interacting with the video content during each second of a period of interest and measuring user involvement during each second.

As noted, in this embodiment I introduce the concepts of aggregating to the house level to filter out duplicate viewing by viewers in the house and of tracking viewing activity by demographic code associated with the house.

By combining the teaching of my co-pending patent applications with the teachings of this application I am able to produce detailed viewing metrics based on a one-second level of granularity for video viewing.

In addition to teaching how to populate the Channel Viewing Detail One-Second Array Data Structure FIG. 14, I then teach how to aggregate from the one-second level to produce one-minute, thirty-minute, and sixty-minute aggregations of viewing activity across all channels and across all time periods of the day with viewing breakouts by demographic group within a geographic area; such aggregations can be used by a reporting application and for further analysis.

Once the data is calculated, the metrics can then be output as (i) data files that can be read by a computer program, (ii) data base tables, (iii) electronic messages, or (iv) a spreadsheet.

A person skilled in the art will readily see the benefits of loading the resulting metrics to a relational data base where additional queries and analytics can be run using standard SQL. In this specification I teach how to produce common industry metrics such as Household Advertising Reach, Impressions, Share, HUT, Rating, and Cumulative Audience using the metrics I create. Additionally, the resulting files may be loaded to other statistical analysis tools or data base structures or tools such as Hadoop. As a nonlimiting example, metrics calculated by the Measurement Engine 200 can be loaded to a data base in support of longer term analysis.

The Measurement Engine 200 presented in this embodiment provides the ability to produce metrics with a level of detail not possible previously. These metrics are described in detail in FIG. 13 (Household Reach Definition Array Data Structure), FIG. 14 (Channel Viewing Detail One-Second Array Data Structure), FIG. 15 (Channel Viewing Detail Array for Aggregation Data Structure), and FIG. 16 (Channel Daily Summary Array for Aggregation Data Structure). The metrics shown in these Figures all provide information useful for understanding viewer behavior; understanding how viewers interact with video programming on traditional television and internet protocol television and other video viewing devices; and understanding ad and program viewing habits. Such metrics will provide valuable information for advertisers, service providers (cable television companies, satellite television companies, and/or internet protocol television providers), advertising agencies, and other interested parties. The Measurement Engine 200 then creates various files containing the calculated metrics in a format suitable for loading to a database or other analytical tool. Finally, as noted, I teach how to code the SQL queries to produce several common industry metrics using this data.

These and other advantages of one or more aspects will become apparent from a consideration of the ensuing description and accompanying drawings.

Data Encryption

To protect the privacy of the viewer and/or to comply with various laws and/or regulations, service providers (cable television companies, satellite television companies, and/or internet protocol television providers) may anonymize and/or encrypt and/or de-identify any data that could identify a specific customer or viewer.

Within the various embodiments presented herein, applying consistent encryption algorithms to the house identifiers and video asset viewing device identifiers (Set-top box id's) in the Raw Video Viewing Event House File Structure FIG. 7 and the downstream files allows the Measurement Engine 200 to produce the metrics identified herein while protecting viewer privacy.

DETAILED DESCRIPTION OF THE DRAWINGS

When reading the information below, it can be appreciated that these are merely samples of table layouts, format and content, and many aspects of these tables may be varied or expanded within the scope of the embodiment. The table layouts, field formats and content, algorithms, and other aspects are what I presently contemplate for this embodiment, but other table layouts, field formats and content, algorithms, etc. can be used. The algorithms are samples and various aspects of the algorithms may be varied or expanded within the scope of the embodiment.

Note on Claims reference in drawings—because of the large number of data fields and new concepts taught in this specification, and because a description in the drawings may not use the exact same words or spelling as the corresponding concept in the claims, the reader will note that in limited cases I have added text preceded by the words “Claims reference” to assist the reader in correlating information in the drawings or detailed description of the drawings with the corresponding information in the claims. These references are not meant in any way to restrict the Claims, but rather to clarify the relationship between the Claims and the Specification.

For many of the metrics shown below, I have suggested what the metric indicates. This is not to limit the purpose of the metric to that one usage, but simply to indicate one of potentially many valuable uses for the metric.

Note that the specification and drawings use certain terms interchangeably. The reader will note this most frequently with the terms set-top box and video asset viewing device. The reader will appreciate that a set-top box is merely a specific kind of video asset viewing device. A smart phone, a tablet device, a gaming console are all examples of video asset viewing device. Thus any discussion herein that refers to a set-top box should be read to also include any kind of a video asset viewing device.

Another example of this is House Demographic Measurement Engine 200 which is often referred to simply as Measurement Engine 200 or simply Engine 200. Another example of this is Viewing Activity which is the same as Tuning Activity.

In one embodiment the House Demographic Measurement Engine 200 can be implemented on processors provided by the INTEL® Corporation under the trademark Core™ i3-2120 using single or multiple processor configurations. The operating system offered by MICROSOFT® Corporation under the trademark WINDOWS 7 Professional can be used as the computer operating system. The Measurement Engine 200 can be implemented in a number of programming languages, including but not limited to, COBOL, C and C++.

I have implemented the Measurement Engine 200 and supporting code in FUJITSU® NetCOBOL® for WINDOWS® version 10.1 developed by Fujitsu® and distributed by Alchemy Solutions Inc. This product is available at http://www.alchemysolutions.com or http://www.netcobol.com. The Measurement Engine 200 and all of the supporting processes have been developed and run on a DELL® Vostro 260 with INTEL® Core™ i3-2120 CPU 3.30 GHz with 4.00 GB of RAM running MICROSOFT® WINDOWS 7 Professional Service Pack 1. The computer was purchased from Dell Computer Corporation. The operating system is from Microsoft.

Although the embodiments described herein enable one of ordinary skill in the art to implement (i.e. build) the Measurement Engine 200 and supporting software, it in no way restricts the method of implementation, the Measurement Engine 200 and supporting software being capable of being implemented on a variety of hardware/software platforms using a variety of development languages, databases, communication protocols and frameworks as will be evident to those of ordinary skill in the art.

Note on Media Measurement Data Model

Cable Television Laboratories, Inc. has published a confidential “Audience Data Measurement Specification” as “OpenCable™ Specifications, Audience Measurement, Audience Measurement Data Specification” having Document Control Number “OC-SP-AMD-D01-120711” copyright © Cable Television Laboratories, Inc. 2012 which contains a Media Measurement Data Model database design which can be used as a source of data to the Measurement Engine 200 which I teach how to build in this application. The teaching in my present application can be implemented in conjunction with that Media Measurement Data Model or with any number of data models as long as the required input data is provided as described herein.

Additionally, my House Demographic Measurement Engine 200 creates files which may be used to load additional tables in a Media Measurement Data Model such as the one published by Cable Television Laboratories, Inc. These files are described in FIGS. 24 to 33.

Note: Numbering in the Drawings—The numbers in the drawings are usually, but not always, in sequential order.

Note on Demographic Types and Codes in the Video Viewing Event File.

This specification assumes that when the Raw Video Viewing Event File is created, the analyst has assigned a Demographic Code to each record. Additionally, there is a Demographic Type which identifies or provides context to the Demographic Code. This is provided to the Engine 200 using Input Parameter file FIG. 50 field Demographic Type 8035. As a nonlimiting example, a Demographic Type might be “INCOME” and then the various Demographic Codes may be values that identify the income level associated with the viewer or the household. The analyst may use up to 60 Demographic Codes in the present embodiment. If the Analyst wanted to create one set of viewing statistics that crossed the entire population, then he could simply assign the same Demographic Code to every video viewing event. A nonlimiting example would be to assign the Demographic Type as “ALL” and the Demographic Code as “ALLRECS”; this would produce one aggregation that crossed the entire population.

FIG. 1 provides an overview of an exemplary process for collecting viewer interaction data derived from a plurality of viewers interacting with video content that was delivered on a plurality of video asset viewing devices delivering content through a network and then loading that data to a Media Measurement Data Base. This figure illustrates several viewers interacting with video asset viewing devices to view content which was delivered to those devices across a network and then to collect viewing activity from those devices.

In this nonlimiting example, the purpose is not to describe in detail the operations of a video content delivery network or a data collection process, but simply to show how the data that is collected from that system can be made available to my PreProcessing Engine 140 for enrichment for use by my House Demographic Measurement Engine 200.

It begins with Viewer Viewing Video Content 9200 who is interacting with a set-top box 9210 and television 9220 as he views video content. The set-top box 9210 interacts with a Video Content Delivery System 9250 which delivers the content across a Network 9230.

It continues with Viewer viewing video content using tablet, smart phone, IP TV, or other video video viewing device 9204 who is interacting with a variety of video viewing devices, including but not limited to tablet, smart phone, IP TV, PC, etc. The video viewing device interacts with a Video Content Delivery System 9250 which delivers the content across a Network 9230.

Video Content Delivery System 9250 then interacts with a Viewer Interaction Data, Data Collection System 9260 which collects all manner of viewer interaction data. The Viewer Interaction Data, Data Collection System 9260 then processes the data as needed to load it to a Media Measurement Data Base 100. The data in the Media Measurement Data Base 100 can then be used as input to my PreProcessing Engine 140 which prepares the data for my House Demographic Measurement Engine 200 as described in FIG. 2.

The reader should take note that the measurement process which I describe in this specification does not require Media Measurement Data Base 100. That is simply one possible way of providing Video Viewing Activity to my measurement process. In one embodiment my process uses Video Viewing Events are provided in a format similar to that described in FIG. 7 Raw Video Viewing Event House File Structure.

FIG. 2 illustrates an exemplary Data Preparation process which is used to prepare the Raw Video Viewing Event data for use by the House Demographic Measurement Engine 200.

The populating of the Media Measurement Database 100 is beyond the scope of this application and so only brief remarks will be made in reference to that. There are video viewing data collection systems that are commonly used in the industry for collecting channel tuning or video viewing event data including switched digital video systems, set top box applications, internet protocol video viewing applications, and other video viewing applications. These systems enable the collection of the video viewing events which can be loaded to a Media Measurement Database 100. From such a database, Raw Video Viewing Events can be extracted in a format similar to that shown in FIG. 7 in order to provide the needed inputs to the Measurement Engine 200. This data can be delivered to the Measurement Engine 200 in any computer readable format including, but not limited to, database tables, flat files, and XML messages. Alternatively, such video viewing events can be collected directly from the source without the need for a Media Measurement Database 100. In such a case, those events can still be provided as Raw Video Viewing Events in a format similar to that shown in FIG. 7 for use by the Measurement Engine 200.

The purpose of the Data Preparation process is to enrich the Raw Video Viewing Event data so that it is ready to be used by the Measurement Engine 200. As part of this process, the PreProcessing Engine 140 will perform a channel mapping process in which the channel call sign in the source file is mapped to an aggregation channel in the enriched file. This enables to aggregation of channels with the same or similar content, such as the standard definition and the high definition version of a channel. The reason for this is that from an advertiser perspective, it often does not matter whether the viewer viewed the ad in standard definition or high definition, but simply that they viewed the ad. Additionally, from the perspective of aggregating content, the analyst may wish to map any number of lightly viewed channels to a single ‘common’ channel because the detail viewing of those channels is not important, but one may not want to discard the viewing entirely. The analyst has complete control of this mapping process—they define the mapping and provide it to the PreProcessing Engine 140 using File Channel Mapping Definition File 120 (FIG. 5).

Proceeding with the review of FIG. 2, the Data Preparation process begins with Media Viewing Measurement Data Preparation Process Overview 400. The first step is to extract the raw video viewing events as per Extract Raw Video Viewing Events from Media Measurement Data Base 105. Those skilled in the art will have no difficulty creating a database query or similar process to extract data from a Media Measurement Database 100 or other source and make it available in a format similar to that defined in Raw Video Viewing Event File 110. The file structure is defined in FIG. 7 Raw Video Viewing Event House File Structure which describes an exemplary format for the input video viewing event data as it exists before enrichment.

Proceeding with the review of FIG. 2, the PreProcessing Engine 140 also requires a channel mapping definition file Channel Mapping Definition File 120 as described in FIG. 5 Channel Mapping Definition File Structure.

Proceeding with the review of FIG. 2, the PreProcessing Engine 140 reads both of these input files and then performs the enrichment process as described more fully in FIG. 4. It then writes the Unsorted Enriched Video Viewing Event File 150 which has a format as shown in FIG. 8 Enriched Video Viewing Event House File Structure. This file is then sorted by Sort Process 160 which sorts the file in order by MARKET-IN 2805, DEMOGRAPHIC-CODE-IN 2810, CHANNEL-CALL-SIGN-TARGET-IN 2815, CHANNEL-AGGREGATION-NBR-IN 2820, HOUSE-ID-IN 2825 producing sorted file Enriched Video Viewing Event File 170 which is ready for processing by the House Demographic Measurement Engine 200.

An alternative embodiment is that when the Raw Video Viewing Event File 110 is created, the field HOUSE-ID-IN 2610 is populated with a Viewer Identifier. This value can then be recorded in the Unsorted Enriched Video Viewing Event File 150 when it is created so that after the Sort Process 160 runs, the file Enriched Video Viewing Event House File Structure 170 actually contains a viewer identifier in the field HOUSE-ID-IN 2825. Loading the data in this manner enables the Measurement Engine 200 to aggregate a viewing information to a viewer level instead of a house level. This can be useful when one viewer controls multiple viewing devices.

Claims Reference: In the claims this is referred to as the house identifier in the Enriched Video Viewing Event House data containing a viewer identifier.

An alternative embodiment is that database extract process may be written such that the file created by the extract process is in a format similar to Enriched Video Viewing Event File 170 which can then be consumed directly by the Measurement Engine 200.

FIG. 3 is a flowchart illustrating an overview of an exemplary process for House Demographic Media Viewing Measurement. The House Demographic Measurement Engine 200 receives five input files: (a) Enriched Video Viewing Event File 170, (b) Household Reach Definition File 180, (c) Demographic Code File 190, (d) Channel Mapping Definition File 120, and (e) an Input Parameter File 125 and then uses a computer to analyze the viewing events in Enriched Video Viewing Event File 170 to produce video viewing metrics, according to one embodiment.

The process works as follows: The Engine 200 first reads the Demographic Code File 190 and loads the data to the arrays in memory as described in FIG. 9 and FIG. 10. Also reference program code B200-LOAD-DEMOGRAPHIC-GROUPS.

The Engine 200 then reads Household Reach Definition File 180 and loads the Reach Definitions to the array in memory as described in FIG. 11, FIG. 12, and FIG. 13. When the Engine 200 is processing the viewing activity, it will compare the house level viewing activity to the Reach definitions and calculate the viewing during each reach period. The system allows numerous Reach periods for each channel to enable tracking of Reach for many advertisements.

Also reference program code B400-LOAD-HOUSE-REACH-DEF.

The Engine 200 then reads Channel Mapping Definition File 120 and loads this to an array in memory as described in FIG. 4 and FIG. 5 and FIG. 6. Note that the actual channel mapping process was completed earlier as described in FIG. 2. In this current step, the Engine 200 is using that same input file (FIG. 5) and loading it to an array in memory (FIG. 6) so that the Channel mapping data is ready to be copied to the list of channels for a Demographic Group. Also reference program code B500-LOAD-CHANNEL-MAPPING-DEF. The Engine 200 also reads the Input Parameter File 125 and saves this information for later processing.

Once these four setup activities are completed, Engine 200 is then ready to process the Enriched Video Viewing Event File 170. The details of this are described in other figures. As output of the processing, the Engine 200 creates these files:

-   -   1) House Reach Detail File 205; reference FIG. 24 for details.     -   2) House Reach Summary File 210; reference FIG. 25 for details.     -   3) Demographic House Reach Summary File 215; reference FIG. 26         for details.     -   4) House Demographic Channel Viewing Detail Minute File 220;         reference FIG. 27 for details.     -   5) House Demographic Channel Minute of Day Summary File 225;         reference FIG. 28 for details.     -   6) House Demographic Channel Viewing Detail Thirty Minute File         250; reference FIG. 29 for details.     -   7) House Demographic Channel Thirty Minute of Day Summary File         255; reference FIG. 30 for details.     -   8) House Demographic Channel Viewing Detail Sixty Minute File         260; reference FIG. 31 for details.     -   9) House Demographic Channel Sixty Minute of Day Summary File         265; reference FIG. 32 for details.     -   10) House Demographic Channel Daily Summary File 270; reference         FIG. 33 for details.     -   Note that the source code included with this application also         includes Five Minute and Fifteen Minute aggregation files which         are similar to the Thirty minute files.

The Measurement Engine 200 as presently configured accepts flat files as input and creates flat files as its output. Those skilled in the art will readily recognize that the Measurement Engine 200 could just as easily read database tables or XML messages or any other computer readable format for its input. It could then produce XML messages or update database tables for its output or produce flat files as it does in the present embodiment.

As noted, a House Reach Detail File 205 (reference FIG. 24) is created as output from the Measurement Engine 200. The Reach Detail File 205 records the Household Reach data that resulted from the video viewing activity. This Reach data is captured in the Household Reach Definition Array Data Structure FIG. 13. By creating the reach file as described in FIG. 24 and then loading this file to a database, an analyst is able to query the advertising or program Reach data to identify all of the homes where an ad or program was viewed; that is the cumulative reach of an ad. When the same ad appears in multiple Reach Period Definitions, this information is used to provide advertisers with a count of the number of different (unique) homes that viewed a particular ad. Such a situation in which the same ad appears in multiple Reach Period Definitions is very common because an advertiser may run the same ad multiple times in one program or across several programs over a period of one or more days. This unique home viewing data can be used for additional analysis. An alternative embodiment could write this Household reach data directly to a database table.

Also as noted, a House Reach Summary File 210 (reference FIG. 25) is created as output from the Measurement Engine 200. The House Reach Detail File 210 records summary reach information identifying the Reach period information along with a count of the number of homes reached. This information provides advertisers with a count of the total number of homes that viewed a particular ad during a give Reach Period. This data can be used for additional analysis.

Also as noted, a Demographic House Reach Summary File 215 (reference FIG. 26) is created as output from the Measurement Engine 200. The Demographic House Reach Summary File 215 records summary reach information identifying the Reach period information along with a count of the number of homes reached broken out by Demographic code. This information provides advertisers with a count of the total number of homes in each demographic group that viewed a particular ad during a give Reach Period. This data can be used for additional analysis.

Also as noted, a House Demographic Channel Viewing Detail Minute File 220 (reference FIG. 27) is created as output from the Measurement Engine 200. The House Demographic Channel Viewing Detail Minute File 220 records aggregate viewing seconds based on unique house level viewing for each channel for each minute of the day, broken out by demographic type and demographic code within market. This information provides the detailed data needed to analyze minute-by-minute viewing patterns for every channel for every minute of the day. This data can be used for additional analysis.

Also as noted, a House Demographic Channel Minute of Day Summary File 225 (reference FIG. 28) is created as output from the Measurement Engine 200. The House Demographic Channel Minute of Day Summary File 225 records aggregate viewing seconds based on unique house level viewing for each minute of the day, summarized across all the channels, broken out by demographic type and demographic code within market. This information provides the detailed data needed to analyze minute-by-minute viewing patterns for all channels combined for every minute of the day. This data can be used as the denominator to calculate the percentage of total viewing that a channel earned during any minute of the day.

Also as noted, a House Demographic Channel Viewing Detail Thirty Minute File 250 (reference FIG. 29) is created as output from the Measurement Engine 200. The House Demographic Channel Viewing Detail Thirty Minute File 250 records aggregate viewing seconds based on unique house level viewing for each channel for each thirty minute segment of the day, broken out by demographic type and demographic code within market. This information provides the data needed to analyze viewing patterns for every channel for every half-hour of the day. This data can be used for additional analysis.

Also as noted, a House Demographic Channel Thirty Minute of Day Summary File 255 (reference FIG. 30) is created as output from the Measurement Engine 200. The House Demographic Channel Thirty Minute of Day Summary File 255 records aggregate viewing seconds based on unique house level viewing for each thirty minute segment of the day, summarized across all the channels, broken out by demographic type and demographic code within market. This information provides the detailed data needed to analyze viewing patterns for all channels combined for every half-hour of the day. This data can be used as the denominator to calculate the percentage of total viewing that a channel earned during any half-hour of the day.

Also as noted, a House Demographic Channel Viewing Detail Sixty Minute File 260 (reference FIG. 31) is created as output from the Measurement Engine 200. The House Demographic Channel Viewing Detail Sixty Minute File 260 records aggregate viewing seconds based on unique house level viewing for each channel for each sixty minute segment of the day, broken out by demographic type and demographic code within market. This information provides the data needed to analyze viewing patterns for every channel for every hour of the day. This data can be used for additional analysis.

Also as noted, a House Demographic Channel Sixty Minute of Day Summary File 265 (reference FIG. 32) is created as output from the Measurement Engine 200. The House Demographic Channel Sixty Minute of Day Summary File 265 records aggregate viewing seconds based on unique house level viewing for each sixty minute segment of the day, summarized across all the channels, broken out by demographic type and demographic code within market. This information provides the detailed data needed to analyze viewing patterns for all channels combined for every hour of the day. This data can be used as the denominator to calculate the percentage of total viewing that a channel earned during any hour of the day.

Finally as noted, a House Demographic Channel Daily Summary File 270 (reference FIG. 33) is created as output from the Measurement Engine 200. The House Demographic Channel Daily Summary File 270 records aggregate viewing seconds based on unique house level viewing for each channel for the entire day, broken out by demographic type and demographic code within market. This information provides the detailed data needed to analyze viewing patterns for each channel to determine what portion of total channel viewing occurs during any part of the day. This data can be used as the denominator to calculate the percentage of total channel viewing that occurs for a given channel during a particular part of the day. As an example, if a channel earned 50,000 viewing seconds during the 7:00 AM hour and 800,000 viewing seconds during the entire day, then this value is used to determine that 6.25% (50,000/800,000) of that channel's total viewing occurred during the 7:00 AM hour.

Each of the output files identified above, 205-270, may be loaded to a data base in support of further analytics. Those with ordinary skill in the art will have no difficulty using common software development tools to develop a process which loads files like the ones shown to a data base or data warehouse in support of additional reporting and analytics. Alternatively, the Measurement Engine 200 could update data base tables having structures similar to those shown in output files 205-270. In this specification I will describe how several common industry metrics can be calculated using this data.

To recap the output files that are created related to Video Program viewing, the Measurement Engine 200 has created Reach files and Program viewing files. Each of these files provides breakouts for Demographic and Geographic attributes thus providing detailed insight into the viewers who are consuming the video content and their location.

The end result is that the analyst has very detailed information regarding viewing activity for each Reach period and for the entire day. The analyst now has a level of understanding of audience viewership never before possible.

Also note that while I teach how to create minute, thirty-minute, and sixty-minute aggregations in this specification, the accompanying source code includes five-minute and fifteen-minute aggregations as well. Those skilled in the art will be easily able to create other aggregations as needed, for example, four-hour aggregations or 30-second aggregations.

FIG. 4 is a flowchart which illustrates an exemplary process for enriching the video viewing event data. FIG. 4 further defines the processing that occurs in PreProcessing Engine 140. By way of overview, this process first loads the Channel Mapping Definition File into an array in memory. Once this is complete, the process then reads each of the raw video viewing events and looks up the channel call sign from the raw video viewing event in the Channel Mapping Data Structure. When a match is found the process assigns the Target Channel to the Video Viewing Event and then, after additional enrichments, writes the enriched record to the file. This mapping process serves two functions: (a) diverse channel calls signs which carry the same video content can be reassigned to a single channel call sign; a nonlimiting example of this is the standard definition and the high definition versions of the same channel; and (b) multiple lightly viewed channels can be combined into a single aggregate channel as might be done with channels carrying similar content; a nonlimiting example of this is music channels.

The process, as part of PreProcessing Engine 140, begins with Enrich Video Viewing Event 400. The first step is to execute Read Channel Mapping File 410 which reads Channel Mapping Definition File 120 which contains the analyst defined channel mappings. The file structure is defined in FIG. 5. When End of File? 420 is No, the process proceeds to Load Channel Mapping Data Structure 430 where the data from the input record is loaded to the Channel Mapping Definition Array Data Structure defined in FIG. 6.

When End of File? 420 is Yes, PreProcessing Engine 140 is done reading the channel mapping definitions and all the data has been loaded to the array (FIG. 6). The PreProcessing Engine 140 now proceeds to processing of the Raw Video Viewing Event File beginning with Read Raw Video Viewing Event File 450 which reads Raw Video Viewing Event File 110. When End of File? 460 is No, the Engine 140 proceeds to Assign Target Channel to Video Viewing Event 470 where the PreProcessing Engine 140 looks up the channel call sign from the raw video viewing event FIG. 7 CHANNEL-CALL-SIGN 2650 to find a match in the Channel Mapping Data Structure matching on CHAN-MAP-CALL-SIGN-SOURCE 2120. When a match is found, the system populates the FIG. 8 CHANNEL-CALL-SIGN-TARGET-IN 2815 with the value from the CHAN-MAP-CALL-SIGN-TARGET 2130. The PreProcessing Engine 140 also populates the FIG. 8 CHANNEL-AGGREGATION-NBR-IN 2820 with the value in CHAN-MAP-AGGREGATION-NBR 2140.

Note: A process very similar to the one defined in FIG. 4 steps 410 to 440 is also used in the Measurement Engine 200 when it is loading the Channel Mapping Data Structure in preparation for measurement activity. Ref Engine 200 program routine B500-LOAD-CHANNEL-MAPPING-DEF.

The remaining fields in Enriched Video Viewing Event House File Structure FIG. 8 are also populated at this time as defined in FIG. 8. The TUNE-IN-SECOND-OF-DAY 2860 and the TUNE-OUT-SECOND-OF-DAY 2875 are both calculated based on the corresponding seconds past midnight. In an alternative embodiment, the tune-in and tune-out second of the day may be provided in the Raw Video Viewing Event File 110.

After populating the fields in FIG. 8, the PreProcessing Engine 140 writes the enriched record as per Write Unsorted Enriched Video Viewing Event File 475 to file Unsorted Enriched Video Viewing Event File 150. This file has the same structure as Enriched Video Viewing Event House File Structure FIG. 8. The process then continues per Continue 480 to read the next record.

When End of File? 460 is Yes, the process is done, Done 465.

At this point, the Unsorted Enriched Video Viewing Event File 150 is sorted by Sort Process 160 creating Enriched Video Viewing Event File 170 as described in FIG. 2; the sorted file is then ready for processing by the House Demographic Analytics Engine 200.

The source code for the PreProcessing Engine 140 is included as part of this Specification. Additionally, the source code for the Sort Process 160 is included as part of this Specification.

Claims Reference: In the claims the process of assigning the target channel call sign to the video viewing event is referred to as the channel call sign being populated by a mapping function which takes a source channel call sign and uses that to lookup a target channel call sign which is then loaded to the channel call sign in the data.

FIG. 5 relates to Channel Mapping definitions.

FIG. 5 illustrates an exemplary record layout for a Channel Mapping Definition File Structure 120 formatted for use as input to the PreProcessing Engine 140 and the House Demographic Measurement Engine 200 with Summary Information followed by the Data Structure description and Sample Data in pipe delimited format, according to one embodiment. This relates to part 120.

The sample data shows various nonlimiting examples: (a) that the analyst is able to define a straight-across mapping (ABC) where the source channel call sign is the same as the target channel call sign, (b) the analyst is able to map two channels to a single channel (both DISNEY and DISNEYHD map to DISNEY). The case where multiple lightly viewed channels map to one group channel is shown by FOOD, SHOP, TRAVEL all mapping to MISC.

FIG. 6 illustrates an exemplary data structure for recording a Channel Mapping Definition in the memory of a computer for use in PreProcessing Engine 140 and for use by the House Demographic Measurement Engine 200, according to one embodiment. This data structure is used in both the PreProcessing Engine 140 and the Measurement Engine 200.

FIG. 7 illustrates an exemplary record layout for a Raw Video Viewing Event House File Structure 110 formatted for use as input to the PreProcessing Engine 140 with Summary Information followed by the Data Structure description, according to one embodiment. This record layout shows the data format prior to enrichment.

FIG. 8 illustrates an exemplary record layout for a Enriched Video Viewing Event House File Structure 170 formatted for use as input to the House Demographic Measurement Engine 200 with Summary Information followed by the Data Structure description, according to one embodiment. This record layout shows the data format after enrichment. Note that the Target Channel Call Sign has been added to the record—Reference CHANNEL-CALL-SIGN-TARGET-IN 2815. Also note that the Channel Aggregation Number has been added for use by the Measurement Engine 200—Reference CHANNEL-AGGREGATION-NBR-IN 2820. Also note that the Tune-in and Tune-out second of day fields have been added for use by the Measurement Engine 200—Reference TUNE-IN-SECOND-OF-DAY 2860 and TUNE-OUT-SECOND-OF-DAY 2875.

FIG. 9 illustrates an exemplary flowchart for loading Demographic Codes to a Data Structure in preparation for use by the House Demographic Measurement Engine 200, so that it can track viewing activity by Demographic Code, according to one embodiment.

The process begins with Load Demographic Codes to Data Structures 550. The process then executes Read Demographic Code File 555 which reads file Demographic Code File 190 as input. The process checks for End of File 560. If it is the end of file, the process is Done 565. If End of File 560 does not detect an end of file condition, then the record that was read is loaded to the Channel Viewing Detail array using Load Demographic Code to Channel Viewing Detail Array for Aggregation Data Structure 570. That same demographic code is then loaded to the Channel Daily Summary array using Load Demographic Code to Channel Daily Summary Array for Aggregation Data Structure 575.

The end result of this process is that the Measurement Engine 200 has loaded the Demographic codes into two Data Structures in the memory of the computer running the engine. This enables the Measurement Engine 200 to track the viewing by Demographic code at a detail level and a summary level.

Single Demographic Group Aggregation

As noted previously, the Analyst may want to create one set of viewing statistics that cross the entire population instead of viewing statistics for every Demographic Group; to do this he simply assigns the same Demographic Code to every video viewing event in file Raw Video Viewing Event File 110. A nonlimiting example would be to assign the Demographic Type as “ALL” and the Demographic Code as “ALLRECS”; this would produce one aggregation that crossed the entire population. In this case, the Demographic Code File 190 would have one record. Such a use of the Measurement Engine 200 will enable the creation of various metrics which require values that are aggregated across the entire population.

FIG. 10 illustrates an exemplary record layout for a Demographic Code File Structure 190 formatted for use as input to the House Demographic Measurement Engine 200 with Summary Information followed by the Data Structure description, according to one embodiment.

FIG. 11 illustrates an exemplary flowchart for loading Household Reach Definitions to a Data Structure in preparation for use by the House Demographic Measurement Engine 200, so that it can track viewing activity for each of the Reach Definition periods, according to one embodiment.

The process begins with Load Household Reach Definition Data Structure 500. The process then executes Read Household Reach Definition File 510 which reads file Household Reach Definition File 180 as input. The process checks for End of File 515. If it is the end of file, the process is Done 520. If End of File 515 does not detect an end of file condition, then the record that was read is loaded to the Household Reach Definition Data Structure (Ref FIG. 13) using Load Household Reach Definition Data Structure 525. The process then proceeds to copy the Demographic code list that was loaded in FIG. 9 to each of the Reach Definitions so that the Measurement Engine 200 is able to track Reach viewing for each demographic code; this copy/load process is done by Load Demographic Code for Household Reach Definition 530.

The end result of this process is that the Measurement Engine 200 has loaded the Reach Definition data to a Data Structure in the memory of the computer running the Engine so that it can then measure the household viewing activity for each house against each of the Reach periods defined in the Reach definition data structure.

FIG. 12 illustrates an exemplary record layout for a Household Reach Definition File Structure 180 formatted for use as input to the House Demographic Measurement Engine 200 with Summary Information followed by the Data Structure description and Sample Data, according to one embodiment. Note that the analyst is able to define any number of Reach definition periods for each Channel Call Sign. Also note that the Analyst may control the duration of the Reach period by specifying the beginning and ending seconds. The Analyst may also control the viewing seconds required to be counted as an exposure. The Channel Call Sign used in the Reach definition should match one of the Target Channel Call Signs that will appear in the Enriched Video Viewing Event File 170 in order to enable a match to occur.

FIG. 13 illustrates an exemplary Household Reach Definition Array Data Structure for use by the House Demographic Measurement Engine 200 with Summary Information followed by the Data Structure description, according to one embodiment. Note that this data structure is setup to allow for Reach Definitions to be recorded for each of 30 different Channel Call Signs. Then note that the structure supports up to 180 Reach Definitions to be recorded for each of the 30 different Channel Call Signs. Also note that the structure is setup to allow 60 Demographic codes for each of the Reach periods for each channel; this provides for detail tracking by demographic code for each Reach period. In another embodiment, the number of Reach Period definitions, Channel Call Signs, and Demographic groups may be adjusted as needed.

By tracking at this level of detail, the Engine 200 provides extensive metrics regarding the ad viewing during the Reach period; such information is extremely useful to advertisers and others.

FIG. 14 illustrates an exemplary Channel Viewing Detail One-Second Array Data Structure for use by the House Demographic Measurement Engine 200 with Summary Information followed by the Data Structure description, according to one embodiment. The Engine 200 will populate this array based on the data in the Enriched Video Viewing Event House File Structure 170 as defined in FIG. 17 and following. Note that this Data Structure is used to aggregate the viewing across multiple devices associated with a House. This aggregation allows the Engine 200 to filter out duplicate viewing in the House (two or more devices tuned to the same channel at the same time) so that an accurate measure of Household Reach can then be calculated. The data is tracked at the one-second level in field CVDS-CHAN-HOUS-VIEWING-COUNT 3045 to provide a fine level of detail in measuring viewing activity.

Claims Reference: By putting this data structure (FIG. 14) into the Measurement Engine 200 it provides computer readable access to the Channel Viewing Detail One-Second Array Data Structure containing viewing activity information which was loaded to the Channel Viewing Detail One-Second Array Data Structure in preparation for analyzing a plurality of viewer interactions resulting from viewers using video asset viewing devices to interact with video content delivered through a network.

Alternative Embodiment

This same Channel Viewing Detail One-Second Array Data Structure could be implemented in a subprogram, a database table, a database structure, or other similar method and still accomplish a similar result.

FIG. 15 illustrates an exemplary Channel Viewing Detail Array for Aggregation Data Structure for use by the House Demographic Measurement Engine 200 with Summary Information followed by the Data Structure description, according to one embodiment.

In the present embodiment the Measurement Engine 200 uses this data structure to track viewing activity for up to 60 different Demographic groups (codes) in a geographic area. Within each demographic group viewing activity can be tracked for up to 600 channels. Then for each of those channels the Measurement Engine 200 can track viewing at one minute, five minute, fifteen minute, thirty minute, and sixty minute aggregation levels. Note that the source code includes five minute and fifteen minute aggregations, but they are not discussed in the Specification or Drawings in order to save space. This detailed tracking provides a rich set of additional viewing metrics in addition to the Reach period metrics. In another embodiment, the number of Demographic groups, Channels, and detail periods may be adjusted as needed.

FIG. 16 illustrates an exemplary Channel Daily Summary Array for Aggregation Data Structure for use by the House Demographic Measurement Engine 200 with Summary Information followed by the Data Structure description, according to one embodiment.

In the present embodiment the Measurement Engine 200 uses this data structure to track viewing activity for up to 60 different Demographic groups (codes) in a geographic area. Within each demographic group viewing activity can be tracked across all the channels at the one minute, five minute, fifteen minute, thirty minute, and sixty minute aggregation levels. Note that the source code includes five minute and fifteen minute aggregations, but they are not discussed in the Specification or Drawings in order to save space. So whereas the Data Structure in FIG. 15 is used to track the viewing at the channel level within Demographic Group, this Data Structure is used to track the viewing across all the channels together within Demographic Group. This detailed tracking also provides a rich set of additional viewing metrics in addition to the Reach period metrics. In another embodiment, the number of Demographic groups and detail periods may be adjusted as needed.

FIG. 17 illustrates an exemplary flowchart providing an overview for processing the enriched video event data by the House Demographic Measurement Engine 200, according to one embodiment.

The process works as follows: The process begins with Process Enriched Video Event File Overview 600. The first step is to do the setup processing by reading the first record in the Enriched video viewing event file where step Read First Enriched Video Viewing Event Record and Save Fields 604 reads a record from file Enriched Video Viewing Event File 170. In this process various fields are saved for comparison later in the process. Reference source code routine D000-PREP-CHAN-TUNING-FILE. Activities that occur in this routine include saving the comparison fields, setting the Demographic subscript, copying the channels to the new demographic row in the array, and setting the Reach array subscript.

Once these initial setup tasks are complete, the Measurement Engine 200 will enter a loop where it will proceed to process each of the Enriched Video Event records. Reference source code routine D120-PROCESS-CHAN-TUNE-DETAIL.

The first step in the loop is to execute Adjust Tune-out Second of Day, Discard Short Tunes 608. Here the system will first adjust the tune-out second of the day as follows: the Measurement Engine 200 will compare the tune duration to the maximum tune duration allowed per the Max Tune Duration 8010 input parameter. For example, this may be 2 hours or 4 hours after which duration the tuning activity is considered zombie tuning. When the tune duration is longer than the allowed limit, the tune-out second is adjusted so that the tune is truncated at the duration specified by the Max Tune Duration 8010 input parameter.

Claims Reference: in the claims this is referred to as the tune-out second of day in the Enriched Video Viewing Event House data containing a value which reflects truncation of the tuning event based upon tune duration.

The next step in processing a record is to discard tunes that are too short. For example, the analyst may want to eliminate channel surfing activity, or he may want to ensure that there is a certain level of engagement by the viewer with the content. This is controlled by accepting as valid only tuning events meeting a minimum duration. This duration is specified using the Min Tune Duration 8015 input parameter. If the tune duration is less than the required duration the tune is not included in the viewing activity.

Claims Reference: in the claims this is referred to as tuning events failing to meet a minimum duration have been removed from the Enriched Video Viewing Event House data.

Reference source code routine D100-PROCESS-CHAN-TUNING-FILE for details on both of these steps.

Once these steps are complete, the Measurement Engine 200 will begin a series of checks. The first check is to validate that the Video Viewing data is from the Market (geographic area) (ref MARKET-IN 2805) that the job is processing, reference Market 8020 input parameter. If it is not, this is considered an error. This step is very basic and is not shown in FIG. 17.

The next step is to compare the Demographic code (ref DEMOGRAPHIC-CODE-IN 2810) to determine whether the demographic code in the current record has changed from the demographic code in the prior record. Reference Same Demo Code 612.

When the Demographic code is the same, the Measurement Engine 200 proceeds to check the Channel Call Sign (ref CHANNEL-CALL-SIGN-TARGET-IN 2815) as per Same Call Sign 616.

When the Channel Call Sign (ref CHANNEL-CALL-SIGN-TARGET-IN 2815) is the same, the Measurement Engine 200 proceeds to check the House identifier (ref HOUSE-ID-IN 2825) as per Same House 620.

When the Demographic code, Channel Call Sign, and House are all the same, the Measurement Engine 200 proceeds to Tabulate Channel Viewing 648 where it will add the viewing activity represented in this Video Viewing Event record into the overall viewing activity for the House. Details of this process are described in FIG. 18.

Once the viewing activity for the House is tabulated, the Measurement Engine 200 proceeds read the next record in file Enriched Video Viewing Event File 170 per Read Next Enriched Video Viewing Event Record 652. If it is not end of file as per End of File? 656, the process proceeds to the start of the loop (to part 608) to begin processing the next record.

If the process does reach the end of the video viewing events per End of File? 656, the process proceeds to Calculate House Reach for Last House 660. The process for calculating House Reach is described in FIG. 19. When the House Reach calculation is done, the process is Done 664.

Returning to the comparison process, step Same House 620, when the House identifier HOUSE-ID-IN 2825 is not the same as the value from the previous Video Viewing Event record (ref part 170 and FIG. 8), the system proceeds to calculate the House Reach per Calculate House Reach 624—see FIG. 19 for details. It then proceeds to Reset Channel View Detail 628—see FIG. 20 for details. It then proceeds to Calculate Values 632 where the Measurement Engine 200 is calculating various record counts. When these steps are completed, the Engine 200 proceeds to Tabulate Channel Viewing 648 where the same steps are described previously are performed.

Returning to the comparison process, step Same Call Sign 616, when the House identifier CHANNEL-CALL-SIGN-TARGET-IN 2815 is not the same as the value from the previous Video Viewing Event record (ref part 170 and FIG. 8), this indicates that the Engine 200 is about to begin processing of a new Channel Call Sign. Before that happens, the Engine 200 must wrap up the work related to the old Call Sign. The first step is to calculate the House Reach per Calculate House Reach 624—see FIG. 19 for details. It then proceeds to Reset Channel View Detail 628—see FIG. 20 for details. It then proceeds to Calculate Values 632 where the Measurement Engine 200 is calculating various record counts. It then resets the Reach array information per Set Reach Array info 644—see FIG. 21 for details. When these steps are completed, the Engine 200 proceeds to Tabulate Channel Viewing 648 where the same steps are described previously are performed.

Returning to the comparison process, step Same Demo Code 612, when the DEMOGRAPHIC-CODE-IN 2810 is not the same as the value from the previous Video Viewing Event record (ref part 170 and FIG. 8), this indicates that the Engine 200 is about to begin processing of a new Demographic group. Before that happens, the Engine 200 must wrap up the work related to the old Demographic group. The first step is to calculate the House Reach per Calculate House Reach 624—see FIG. 19 for details. It then proceeds to Reset Channel View Detail 628—see FIG. 20 for details. It then proceeds to Calculate Values 632 where the Measurement Engine 200 is calculating various record counts. It then resets the Demographic info per Set Demo info 636—see FIG. 22 for details. It then copies the list of Channels to the new row in the Channel Viewing Detail array per Copy Channels to New Demo 640—See FIG. 23 for details. It then sets the Reach array information per Set Reach Array info 644—see FIG. 21 for details. When these steps are completed, the Engine 200 proceeds to Tabulate Channel Viewing 648 where the same steps described previously are performed.

Calculate Values 632 includes the following calculations:

DEMO-CODE-CHANNEL-COUNT FIG. 15 3245 is incremented by 1 when the Channel changes using this formula:

ADD 1 TO DEMO-CODE-CHANNEL-COUNT (DEMO-SUB, CHAN-SUB) 3245

Ref Source Code Routine: D120-PROCESS-CHAN-TUNE-DETAIL

DEMO-CODE-CHANNEL-HOUSE-COUNT FIG. 15 3250 is incremented by 1 when the House id changes using this formula:

ADD 1 TO DEMO-CODE-CHANNEL-HOUSE-COUNT (DEMO-SUB, CHAN-SUB) 3250

Ref Source Code Routine: D120-PROCESS-CHAN-TUNE-DETAIL

DEMO-CODE-CHANNEL-TUNE-COUNT FIG. 15 3255 is incremented by 1 for each video viewing event for the Channel using this formula:

ADD 1 TO DEMO-CODE-CHANNEL-TUNE-COUNT (DEMO-SUB, CHAN-SUB) 3255

Ref Source Code Routine: D120-PROCESS-CHAN-TUNE-DETAIL

At the conclusion of FIG. 17 processing, the Measurement Engine 200 has read the entire Video Viewing Event File 170 and it has calculated Reach information for every House represented in the file. Along the way, the Engine 200 has loaded each home's data into the Channel Viewing Detail One-Second Array Data Structure FIG. 14 so that it could calculate House Reach using the one second level data in that Data Structure. Additionally, the Engine 200 has tabulated the FIG. 15 fields One Minute Channel Viewing AGGR-CHAN-VIEW-SEC-THIS-MINUTE 3280, Total unique homes viewing at the beginning (first second) of the minute AGGR-CHAN-VIEW-AT-BEG-OF-MINUTE 3282, and Total unique homes viewing at the middle (30th second) of the minute AGGR-CHAN-VIEW-AT-MID-OF-MINUTE 3284 in the Channel Viewing Detail Array for Aggregation Data Structure FIG. 15 in preparation for subsequent aggregation processing.

FIG. 18 illustrates an exemplary flowchart describing the process for tabulating channel viewing activity by the House Demographic Measurement Engine 200, according to one embodiment. As noted in the description of FIG. 17, the Tabulate Channel Viewing 648 process is called as part of processing each Video Viewing Event. This process uses the Tune-in second of the day (ref FIG. 8 TUNE-IN-SECOND-OF-DAY 2860) and the Tune-out second of the day (Ref FIG. 8 TUNE-OUT-SECOND-OF-DAY 2875). Also recall from FIG. 17 that the Tune-out second of the day may have been adjusted, based on input parameter Max Tune Duration 8010, to truncate long running video viewing events.

Also note that prior to entering this routine, the Engine 200 has set the values of the Demo-sub and the Chan-sub. As noted in FIG. 15, there are up to 60 values allowed for CHAN-VD-DEMO-CODE 3215. Demo-sub controls the row of that array thus identifying the demographic group into which the values will be added.

Also, as noted in FIG. 15, there are up to 600 values allowed for CHAN-VD-CHANNEL-CALL-SIGN-TRGT 3230. Chan-sub controls the row of that array thus identifying the channel into which the values will be added.

Proceeding with the review of FIG. 18, the process begins with Tabulate Channel Viewing 648. The Engine 200 then performs a loop in which it loops through each of the seconds represented in the adjusted video viewing event from the tune-in second to the adjusted tune-out second. The first step in the loop is to calculate the Minute-sub which is used to control bucket into which the minute level viewing activity will be aggregated; the formula ((Second-sub−1)/60)+1 truncated will yield the minute of the day which contains the second being processed.

To calculate the AGGR-CHAN-VIEW-AT-BEG-OF-MINUTE 3282 and AGGR-CHAN-VIEW-AT-MID-OF-MINUTE 3284, the following formulas are used:

 Compute second-for-beg-of-minute = minute-sub * 60  Compute second-for-mid-of-minute = second-for-beg-of-minute + 30  If second-sub = second-for-beg-of-minute   Add 1 to AGGR-CHAN-VIEW-AT-BEG-OF-MINUTE (DEMO-SUB, CHAN-SUB, MINUTE-  SUB) 3282  End-if  If second-sub = second-for-mid-of-minute   Add 1 to AGGR-CHAN-VIEW-AT-MID-OF-MINUTE (DEMO-SUB, CHAN-SUB, MINUTE-  SUB) 3284  End-if Reference program code routine: D200-TABULATE-CHANNEL-VIEWING

The Engine 200 then tests to see whether the process is calculating ‘All’ viewing seconds or ‘Unique’ viewing seconds. This is based on the input parameter FIG. 50 All or Unique Seconds 8025.

For ‘All’ viewing seconds, the Engine 200 simply adds 1 to the House Viewing Count for the second (Ref FIG. 14 CVDS-CHAN-HOUS-VIEWING-COUNT 3045) and to Demo-Channel-Minute Viewing Seconds (Ref FIG. 15 AGGR-CHAN-VIEW-SEC-THIS-MINUTE 3280). When second-sub=second-for-beg-of-minute, the Engine 200 also increments AGGR-CHAN-VIEW-AT-BEG-OF-MINUTE (DEMO-SUB, CHAN-SUB, MINUTE-SUB) 3282. When second-sub=second-for-mid-of-minute, the Engine 200 also increments AGGR-CHAN-VIEW-AT-MID-OF-MINUTE (DEMO-SUB, CHAN-SUB, MINUTE-SUB) 3284 as shown in the program code routine D200-TABULATE-CHANNEL-VIEWING.

For ‘Unique’ viewing seconds, the Engine 200 will only tally the viewing seconds if the value in the array position (Ref FIG. 14 CVDS-CHAN-HOUS-VIEWING-COUNT 3045) is still zero which means that no device in the house has been identified as viewing that Channel during that second of the day. A value of 1 or more means that the Engine 200 has already determined that a viewing device in that house has already been flagged as viewing that channel during that second of the day; in this case, the Engine 200 can simply increment the count of Duplicate viewing seconds.

So when the count of viewing seconds (Ref FIG. 14 CVDS-CHAN-HOUS-VIEWING-COUNT 3045) is still zero, the Engine 200 simply adds 1 to the House Viewing Count for the second (Ref FIG. 14 CVDS-CHAN-HOUS-VIEWING-COUNT 3045) and to Demo-Channel-Minute Viewing Seconds (Ref FIG. 15 AGGR-CHAN-VIEW-SEC-THIS-MINUTE 3280). When second-sub=second-for-beg-of-minute, the Engine 200 also increments AGGR-CHAN-VIEW-AT-BEG-OF-MINUTE (DEMO-SUB, CHAN-SUB, MINUTE-SUB) 3282. When second-sub=second-for-mid-of-minute, the Engine 200 also increments AGGR-CHAN-VIEW-AT-MID-OF-MINUTE (DEMO-SUB, CHAN-SUB, MINUTE-SUB) 3284 as shown in the program code routine D200-TABULATE-CHANNEL-VIEWING.

At the end of the loop, all of the viewing activity represented in the video viewing event has been accounted for and aggregated into the Channel Viewing Detail One-Second Array Data Structure FIG. 14 and then Channel Viewing Detail Array for Aggregation Data Structure FIG. 15.

FIG. 19 illustrates an exemplary flowchart describing the process for calculating house reach by the House Demographic Measurement Engine 200, according to one embodiment. As noted in the description of FIG. 17, the Calculate House Reach 624 process is called after all of the Video Viewing Events for a House have been loaded to the Channel Viewing Detail One-Second Array Data Structure FIG. 14. Whether through a change in the House id (ref Enriched Video Viewing Event House File Structure FIG. 8 HOUSE-ID-IN 2825), or the Channel Call Sign (ref FIG. 8 CHANNEL-CALL-SIGN-TARGET-IN 2815), or the Demographic code (ref FIG. 8 DEMOGRAPHIC-CODE-IN 2810), the Engine 200 has determined that it is time to analyze the Reach viewing for the House.

Also note that prior to calling this routine, the Engine 200 has in FIG. 17 set the Reach array info in step Set Reach Array Info 644 where the Reach Period subscript is set. Also recall that the Household Reach Definition Array Data Structure FIG. 13 allows up to 30 different Channels (ref FIG. 13 REACH-DEF-CALL-SIGN 2310) for which Reach periods can be defined. FIG. 13 also allows up to 180 Reach Definitions (ref FIG. 13 field REACH-DEF-PERIOD-ID 2320 through field REACH-DEF-ASSET-ID 2370) to be recorded for each of the 30 different Channel Call Signs.

Prior to entering Calculate House Reach 624, the Channel 2310 has been determined and the appropriate subscript is set. This routine then is looping through each of the Reach Period Definitions (up to 180 of them) for that Channel 2310.

Proceeding with the review of FIG. 19, the first step is Calculate House Reach 624. The Engine 200 then performs a loop (process 625) in which it loops through each Reach Period Definition associated with the Channel 2310. Each Reach Period Definition contains a Beginning Second of the day (ref FIG. 13 REACH-DEF-BEG-SEC-OF-DAY 2330) and an Ending Second of the day (ref FIG. 13 REACH-DEF-END-SEC-OF-DAY 2340) which together define the bounds of the Reach Period. The Engine 200 will use these bounds to set up a loop in which it tabulates the viewing activity of the channel during each second of the Reach Period. Whenever the House has viewing during that second, this is added to the total.

-   -   Claims Reference: By examining viewing activity during each         second of the Reach Period, this enables measurement of the         viewing activity during the Reach Period to identify Households         having viewing activity during each said Reach Period defined by         the Reach Period Definitions.     -   Claims Reference: By examining viewing activity during each         second of the Reach Period, this enables the Engine 200 to         compare viewing activity in each Bucket based upon the window of         time defined by the reach period begin second of the day and         reach period end second of the day to identify homes with less         than sufficient viewing to qualify as an Exposure according to         the Reach Period Definition.     -   Claims Reference: By examining viewing activity during each         second of the Reach Period, this enables the Engine 200 to         compare viewing activity in each Bucket based upon the window of         time defined by the reach period begin second of the day and         reach period end second of the day to identify homes with         sufficient viewing to qualify as an Exposure according to the         Reach Period Definition.

At the end of the Loop, the Engine 200 compares the number of seconds where there was viewing activity to the Minimum seconds required for an exposure (ref FIG. 13 REACH-DEF-MIN-SEC-EXPOSU 2350). When the threshold is met, the Homes Reach Count (ref FIG. 13 HOMES-REACHED-COUNT 2380) is incremented. At the same time, the Demographic Homes Reached Count (ref FIG. 13 DEMO-CODE-HOMES-REACHED-COUNT 2395) is incremented for the Demographic code that was previously identified. Thus the Engine 200 has tracked Reach Period viewing at an aggregate level across all demographic codes and at the demographic code level for each individual demographic code.

-   -   Claims Reference: By comparing total house viewing activity         during the Reach Period to the amount of viewing required to         earn an exposure, this enables the tracking of house level         exposures as recorded in Homes Reached Count for each Reach         Period.     -   Claims Reference: By comparing total house viewing activity for         a house identified by a demographic code during the Reach Period         to the amount of viewing required to earn an exposure, this         enables the tracking of house level exposures categorized by a         plurality of Demographic Codes such that Homes Reached Count is         tracked for each Demographic Code for each Reach Period         Definition.

The Engine 200 then proceeds to the next Reach Period incrementing the Reach-Def-Period-Sub and the process is repeated for the new Reach period. This continues until all of the Reach Period Definitions for the Channel have been processed. The Engine then proceeds to Done 626.

FIG. 20 illustrates an exemplary flowchart describing the process for resetting the channel view detail fields by the House Demographic Measurement Engine 200, according to one embodiment. As noted in the description of FIG. 17, the Reset Channel View Detail 628 process is called after performing process Calculate House Reach 624.

Proceeding with the review of FIG. 20, the first step is Reset Channel View Detail 628. The Engine 200 then performs a loop (process 629) in which it loops through each of the seconds of viewing activity (Ref field CVDS-CHAN-HOUS-VIEWING-COUNT 3045) in the Channel Viewing Detail One-Second Array Data Structure FIG. 14 that was captured for the House with the objective of resetting the array to zero in preparation for processing the video viewing activity for the next house. The first and last viewing seconds are identified by the program variables House First Viewing Second and House Last Viewing Second. After the loop is complete, the process is Done 630. Source program reference is D600-RESET-CHAN-VIEW-DTL-SECND.

In an alternative embodiment, the Engine 200 could simply move zero to the array for the 86400 seconds of the day (Ref field CVDS-CHAN-HOUS-VIEWING-COUNT 3045).

FIG. 21 illustrates an exemplary flowchart describing the process for setting the reach definition flag and subscript value in preparation for use by the House Demographic Measurement Engine 200, according to one embodiment. As noted in the description of FIG. 17, the Set Reach Array info 644 process is called after the Channel changes or the Demographic code changes.

Proceeding with the review of FIG. 21, the first step is Set Reach Array info 644. The Engine 200 then performs a loop (process 646) in which it loops through each of the Channels (Ref field REACH-DEF-CALL-SIGN 2310) in the Household Reach Definition Array Data Structure FIG. 13. Recall that these channels define the channels on which the Engine 200 will look for Reach Period viewing activity. When there is a match between the Channel in the Reach Definition (Ref field REACH-DEF-CALL-SIGN 2310) and the Channel in the Enriched Video Viewing Event House File Structure field FIG. 8 CHANNEL-CALL-SIGN-TARGET-IN 2815, then the Channel is identified as having a Reach Period and the subscript associated with that channel is saved for use in subsequence processing. When a matching channel is found, the process is Done 648.

In an alternative embodiment, the Engine 200 could simply scan through the entire list of Reach Period channels for every Channel in the input file. The present embodiment provides a more efficient process because the act of looking for the Reach Period channel is only done as needed.

FIG. 22 illustrates an exemplary flowchart describing the process for setting the demographic code subscript value in preparation for use by the House Demographic Measurement Engine 200, according to one embodiment. As noted in the description of FIG. 17, the Set Demo info 636 process is called after the Demographic code changes.

Proceeding with the review of FIG. 22, the first step is Set Demo info 636. The Engine 200 then performs a loop (process 637) in which it loops through each of the Demographic Codes (Ref field CHAN-VD-DEMO-CODE 3215) in the Channel Viewing Detail Array for Aggregation Data Structure FIG. 15 looking for a match between the value in CHAN-VD-DEMO-CODE 3215 and DEMOGRAPHIC-CODE-IN 2810. Recall that these demographic codes where loaded to the Data Structure during FIG. 9 processing. When there is a match between the two fields, then the subscript associated with that Demographic Code is saved for use in subsequence processing. When a matching Demographic Code is found, the process is Done 638.

In an alternative embodiment, the Engine 200 could simply scan through the entire list of Demographic Codes for every Demographic Code in the input file. The present embodiment provides a more efficient process because the act of looking for the Demographic Code is only done as needed.

FIG. 23 illustrates an exemplary flowchart describing the process for copying the channel information to a new demographic code grouping in preparation for use by the House Demographic Measurement Engine 200, according to one embodiment. As noted in the description of FIG. 17, the Copy Channels to New Demo 640 process is called after executing Set Demo info 636 which was run when the Demographic code changes.

Proceeding with the review of FIG. 23, the first step is Copy Channels to New Demo 640. The Engine 200 then performs a loop (process 641) in which it loops through each of the rows in the Channel Mapping Definition Array Data Structure FIG. 6 so that it can copy the channel information to the Channel Viewing Detail Array for Aggregation Data Structure FIG. 15.

The Engine 200 uses the Channel Aggregation number (Ref CHAN-MAP-AGGREGATION-NBR 2140) to identify the subscript of the row to which the channel information will be copied. Having done that, the Engine 200 copies:

FIG. 6 CHAN-MAP-CALL-SIGN-TARGET 2130 to FIG. 15 CHAN-VD-CHANNEL-CALL-SIGN-TRGT 3230

FIG. 6 CHAN-MAP-AGGREGATION-NBR 2140 to FIG. 15 CHAN-VD-MAP-AGGREGATION-NBR 3235

When all the Channels have been copied, the process is Done 642.

Note: Fields CHAN-MAP-CALL-SIGN-TARGET 2130 and CHAN-MAP-AGGREGATION-NBR 2140 are populated by the Measurement Engine 200 when it is loading the Channel Mapping Data Structure in preparation for measurement activity. Ref Engine 200 program routine B500-LOAD-CHANNEL-MAPPING-DEF. The population process is similar to what occurs in FIG. 4 steps 410 to 440.

Review of FIGS. 24-33.

I will now review FIGS. 24-33.

These figures provide the record layouts for the various files that are created by the Measurement Engine 200 as a result of calculating video asset viewing activity. These files are structured such that they can be loaded to a database where a reporting application can be developed. To assist the reader in implementing such a system I have provided suggested Table names. The reader will note that while this embodiment shows that these outputs are created as flat files, another embodiment may insert to or update a data base table to record this information. Yet another embodiment may show XML messages or any other computer readable format.

For each of FIGS. 24-33, the reader will find a block of information entitled Summary Information. It provides a Short name of the file/data, a Table Name which is a suggested name which can be assigned to the table to which this file is loaded in the database, the Output file name assigned by Measurement Engine 200, a Record description, and the Specification File Name. With these various elements, the reader has an start-to-finish view of each file. After the Summary Information, the reader will find the Record Layout which lists the Name of the individual fields, data type, size, and description or definition for each field in the file.

For each file, in the DESCRIPTION field under the Record Layout, I have specified how the field is populated or where the field is populated from. The DESCRIPTION field is intended to augment the description found in the source field.

The reader will also find the heading Query Source Code Ref which is followed by the title of a query that can be found in the attached Query Source Code Ref file which is included with this specification. The reader will appreciate that there are multiple ways to query the various tables to produce the results shown. All such query variations fall within the spirit and scope of this teaching.

FIG. 24

illustrates summary information and an exemplary record layout for the House Reach Detail file 205 which is produced by the Measurement Engine 200 as a result of calculating Reach activity at the house level.

Discussion of FIG. 24 Data Usage

Commercial Schedule Cumulative Audience

The file in FIG. 24 can be loaded to a database table with a layout matching the FIG. 24 file structure for additional analytics. Those skilled in the art will have no difficulty loading such a table with daily data for multiple days.

One nonlimiting example of using this data is to calculate Commercial Schedule Cumulative Audience for an Advertising Campaign which is running a particular ad multiple times over a period of days. The Advertising Campaign is identified by field HRD-REACH-CAMPAIGN-ID 4050. The ad being aired is identified by field HRD-REACH-ASSET-ID 4055. Commercial Schedule Cumulative Audience is the number of unique households that were exposed to the ad during the campaign; this information is important to an advertiser. Commercial Schedule Cumulative Audience requires the detail viewing data including the House identifier and the Reach Period information in order to be calculated; once the data is aggregated to counts, the detail needed to calculate Cumulative Audience is lost.

-   -   Note: Exposed means that the household had sufficient viewing of         the ad to meet the viewing seconds exposure requirement.

So once this data has been loaded to a database table such as HOUSE-REACH-DETAIL, a query like the following will produce the Commercial Schedule Cumulative Audience for a particular demographic group that may have viewed the ad run as part of a Campaign during a defined time period:

Select count (distinct HRD_REACH_VD_HOUSE_ID) 4035

From HOUSE_REACH_DETAIL

Where HRD_TUNING_ACTIVITY_DATE 4010 in (list of desired dates)

And HRD_REACH_VD_MARKET 4020=user specified market value

Claims Reference: This provides the Commercial Schedule Cumulative Audience metric.

Query Source Code Ref: Commercial Schedule Cumulative Audience

Commercial Schedule Cumulative Audience House List

In addition to producing the count of Commercial Schedule Cumulative Audience, an advertiser may want to have a list of House id's for a particular demographic group that may have viewed the ad during a defined time period. A query like the following will produce the Commercial Schedule Cumulative Audience House List for a particular demographic group that may have viewed the ad run as part of a Campaign during a defined time period:

Select distinct HRD-REACH-VD-HOUSE-ID 4035

From HOUSE-REACH-DETAIL

Where HRD-TUNING-ACTIVITY-DATE 4010 in (list of desired dates)

FIG. 25

illustrates summary information and an exemplary record layout for the House Reach Summary file 210 which is produced by the Measurement Engine 200 as a result of calculating Reach activity at the house level.

Discussion of FIG. 25 Data Usage

Impressions for Multiple Reach Periods

The file in FIG. 25 can be loaded to a database table with a layout matching the FIG. 25 file structure for additional analytics. Those skilled in the art will have no difficulty loading such a table with daily data for multiple days.

One nonlimiting example of using this data is to calculate Impressions for an Advertising Campaign which is running a particular ad multiple times over a period of days. The Advertising Campaign is identified by field HRS-REACH-CAMPAIGN-ID 4235. The ad being aired is identified by field HRS-REACH-ASSET-ID 4240. Impressions is the number of total gross (including duplicate) viewings of the ad (where the viewing met the minimum number of seconds to be considered an exposure) across all the households during the campaign; this information is important to an advertiser.

So once this data has been loaded to a database table such as HOUSE-REACH-SUMMARY, a query like the following will produce the Impressions count across all demographic groups that may have viewed the ad during a defined time period:

Select Sum (HRS-HOMES-REACHED-COUNT) 4260

Claims Reference: This provides the metric Impressions for Multiple Reach Periods.

Query Source Code Ref: Impressions for Multiple Reach Periods

Impressions for a Particular Reach Period Another nonlimiting example of using this data is to calculate Impressions for a Particular Reach Period which might be an ad airing on a single channel at a point in time. The Channel is identified by HRS-REACH-VD-CHAN-CALL-SIGN 4225. The Reach Period is identified by HRS-REACH-PERIOD-ID 4230. The Advertising Campaign may be identified by field HRS-REACH-CAMPAIGN-ID 4235. The ad being aired is identified by field HRS-REACH-ASSET-ID 4240. Impressions for a Particular Reach Period is the number of total gross viewings of the ad where the viewing met the minimum number of seconds to be considered an exposure across all the households during the Reach Period; this information is important to an advertiser. This tells the advertiser how many households were exposed to his ad when it ran on a certain channel on a certain date at a certain time. Impressions for a Particular Reach Period is the same thing as Commercial Cumulative Audience which is answering the question of how many viewers saw an ad that was aired on a channel at a particular time.

So once this data has been loaded to a database table such as HOUSE-REACH-SUMMARY, a query like the following will produce the Impressions for a Particular Reach Period across all demographic groups that may have viewed the ad during a defined time period:

The file in FIG. 26 can be loaded to a database table with a layout matching the FIG. 26 file structure for additional analytics. Those skilled in the art will have no difficulty loading such a table with daily data for multiple days.

One nonlimiting example of using this data is to calculate Demographic Group Impressions for Multiple Reach Periods for an Advertising Campaign which is running a particular ad multiple times over a period of days, targeted to a certain demographic group. The Advertising Campaign is identified by field DHRS-REACH-CAMPAIGN-ID 4445. The ad being aired is identified by field DHRS-REACH-ASSET-ID 4450. Demographic Group Impressions is the number of total gross (including duplicate) viewings of the ad where the viewing met the minimum number of seconds to be considered an exposure during the campaign by households identified by the proper demographic code; this information is important to an advertiser.

FIG. 27

illustrates summary information and an exemplary record layout for the House Demographic Channel Viewing Detail Minute file 220 which is produced by the Measurement Engine 200 as a result of calculating house level video asset viewing activity at the one-minute level for each channel.

Discussion of FIG. 27 Data Usage

Demographic Group Average Audience One Minute Timeframe

The file in FIG. 27 can be loaded to a database table with a layout matching the FIG. 27 file structure for additional analytics. Those skilled in the art will have no difficulty loading such a table with daily data for multiple days.

One nonlimiting example of using this data is to calculate Demographic Group Average Audience for any minute of time or for multiple minutes of time. Demographic Group Average Audience is an estimate of how many households identified by a particular demographic group are viewing a certain channel during a certain minute. It is calculated as total viewing seconds for the chosen channel during the period/the period duration in seconds. In terms of the fields in FIG. 27, it is CVDM-AGGR-CHN-VIEW-SEC-THS-MIN 4645/60 seconds in the minute. If the time period was 3 minutes, then the denominator would be 180 seconds.

So once this data has been loaded to a database table such as HOUSE_DEMO_CHAN_VW_DETL_01_MIN, a query like the following will produce the Demographic Group Average Audience One Minute Timeframe for a demographic group that may have viewed a certain channel during a particular minute on a certain date:

Select CVDM-AGGR-CHN-VIEW-SEC-THS-MIN 4645/60 as “Demo Group Avg Audience”

From HOUSE_DEMO_CHAN_VW_DETL_01_MIN

Where CVDM-TUNING-ACTIVITY-DATE 4610=User specified date

Demographic Group Average Rating One Minute Timeframe

Another use of the FIG. 27 data is to calculate Demographic Group Average Rating which is (Demographic Group Average Audience/Universe Estimate)*100 (see Definitions). The Demographic Group Average Rating is the percentage of the potential audience that this one minute segment earned. It is potential audience because the Universe Estimate is the total universe or the total population of TV households in a geographic area, but it is not likely that every single house is viewing television at the time of the measurement.

So once this data has been loaded to a database table such as HOUSE_DEMO_CHAN_VW_DETL_01_MIN, a query like the following will produce the Demographic Group Average Rating One Minute Timeframe for a demographic group that may have viewed a certain channel during a particular minute on a certain date:

Select (CVDM-AGGR-CHN-VIEW-SEC-THS-MIN 4645/Universe-Estimate)*100 as “Demo Group Avg Rating”

From HOUSE_DEMO_CHAN_VW_DETL_01_MIN,

Discussion of FIG. 28 Data Usage

Demographic Group Households Using Television One Minute Timeframe

The file in FIG. 28 can be loaded to a database table with a layout matching the FIG. 28 file structure for additional analytics. Those skilled in the art will have no difficulty loading such a table with daily data for multiple days.

One nonlimiting example of using this data is to calculate Demographic Group Households Using Television for any minute of time or for multiple minutes of time. Demographic Group Households Using Television is an estimate of how many households identified by a particular demographic group are viewing any television channel during a certain minute. It is calculated as total viewing seconds by the Demographic Group across all channels during the period/the period duration in seconds. In terms of the fields in FIG. 28, it is MODS-AGGR-VIEWING-SECONDS 4840/60 seconds in the minute. If the time period was 3 minutes, then the denominator would be 180 seconds.

So once this data has been loaded to a database table such as HOUSE_DEMO_CHAN_DAY_01_MIN_SUM, a query like the following will produce the Demographic Group Households Using Television One Minute Timeframe for a demographic group during a particular minute on a certain date:

Select MODS-AGGR-VIEWING-SECONDS 4840/60 as “Demo Group Homes Using TV”

Aggregate Households Using Television One Minute Timeframe

The file in FIG. 28 can be loaded to a database table with a layout matching the FIG. 28 file structure for additional analytics. Those skilled in the art will have no difficulty loading such a table with daily data for multiple days.

One nonlimiting example of using this data is to calculate Aggregate Households Using Television for any minute of time or for multiple minutes of time. Aggregate Households Using Television is an estimate of how many households across the entire population are viewing any television channel during a certain minute. If the Engine 200 is used to aggregate the data across the entire population as discussed in FIG. 9 Single Demographic Group Aggregation, then there is one Demographic Code with the value “ALLRECS” which contains a single aggregation that crosses the entire population. In this case, Aggregate Households Using Television is calculated as total viewing seconds by the population across all channels during the period/the period duration in seconds. In terms of the fields in FIG. 28, it is MODS-AGGR-VIEWING-SECONDS 4840/60 seconds in the minute. If the time period was 3 minutes, then the denominator would be 180 seconds.

So once this data has been loaded to a database table such as HOUSE_DEMO_CHAN_DAY_01_MIN_SUM, a query like the following will produce the Aggregate Households Using Television One Minute Timeframe for the full population during a particular minute on a certain date:

Select MODS-AGGR-VIEWING-SECONDS 4840/60 as “Aggregate Homes Using TV”

From HOUSE_DEMO_CHAN_DAY_01_MIN_SUM

Query Source Code Ref: Aggregate Households Using Television One Minute Timeframe

Households Using Television Percent One Minute Timeframe Another nonlimiting example of using this data is to calculate Households Using Television Percent for any minute of time or for multiple minutes of time. Households Using Television Percent is an estimate of the percentage of households across the entire population viewing any television channel during a certain minute or minutes. So following the process for calculating Aggregate Households Using Television discussed above, we can build on that to calculate Households Using Television Percent by simply dividing Aggregate Households Using Television by Universe Estimate, then multiple by 100 to make this a percentage. A query like the following will produce the Households Using Television Percent One Minute Timeframe for the full population during a particular minute on a certain date:

Select ((MODS-AGGR-VIEWING-SECONDS 4840/60)/Universe-Estimate)*100 as “Homes

Discussion of FIG. 27 and FIG. 28 Combined Data Usage

Demographic Group Average Audience Share One Minute Timeframe

After loading both the file in FIG. 27 and the file in FIG. 28, additional metrics that combine data from both files can be calculated.

One nonlimiting example of using this data is to calculate Demographic Group Average Audience Share for any minute of time or for multiple minutes of time. Demographic Group Average Audience Share is based on the amount of viewing that one channel has compared to all the viewing occurring during that minute. This is calculated as Demographic Group Average Audience [from FIG. 27]/Demographic Group Households Using Television [from FIG. 28]. By combining those two queries two produce a query like the following, we can produce Demographic Group Average Audience Share One Minute Timeframe for a demographic group for a particular channel during a particular minute on a certain date:

Select CVDM-AGGR-CHN-VIEW-SEC-THS-MIN 4645/60 as “Demo Group Avg Audience”,

MODS-AGGR-VIEWING-SECONDS 4840/60 as “Demo Group Homes Using TV”,

FIG. 34 illustrates an exemplary flowchart providing an overview of the process for calculating the viewing metrics. The process begins with Calculate Viewing Metrics 700. The Measurement Engine 200 then proceeds to calculate the one-minute metrics per Calculate One Minute Metrics 710. The next step is to calculate the thirty minute metrics per Calculate Thirty Minute Metrics 740. The next step is to calculate the sixty minute metrics per Calculate Sixty Minute Metrics 750. The next step is to calculate the channel metrics per Calculate Channel Metrics 760. At this point the process is done per Done 770. The detail for each of these steps is provided in subsequent figures.

Review of FIGS. 35-40.

I will now review FIGS. 35-40.

These figures provide the exemplary flowcharts describing how the Measurement Engine 200 calculates the viewing metrics. It is helpful when reviewing these Flowcharts to envision a three dimensional table in the memory of the computer as follows: Demographic Group (Ref FIG. 15 CHAN-VD-DEMO-CODE 3215), Channel (Ref FIG. 15 CHAN-VD-CHANNEL-CALL-SIGN-TRGT 3230), and Minute (Ref FIG. 15 AGGR-CHAN-VIEW-SEC-THIS-MINUTE 3280) with the demographic groups as sheets, the Channels as rows on each sheet, and the minutes as columns across. Then the processes described in FIGS. 35 to 40 are each called once for each Demographic Code. Ref Source Code Routine A100-Control-process for details.

FIG. 35 illustrates an exemplary flowchart for calculating the one-minute viewing metrics. The process begins with Calculate One Minute Metrics 710. The objective of this routine is to Calculate Aggregate Viewing During Each Minute of Day. This routine is called once for each Demographic Code.

The process proceeds to Calculate Aggregate Viewing During Each Minute of Day 712. Once inside this routine, the outer loop goes across the minutes of the day, the inner loop goes down the channels. As the Engine 200 goes down the Channels (Ref FIG. 15 CHAN-VD-CHANNEL-CALL-SIGN-TRGT 3230), it is adding up the aggregate viewing seconds from each channel+minute (Ref FIG. 15 AGGR-CHAN-VIEW-SEC-THIS-MINUTE 3280). The result is being saved in the Minute level aggregate viewing seconds (Ref FIG. 16 MINUTE-AGGR-VIEWING-SECONDS 3420). When the Engine 200 completes adding up all the viewing seconds for one channel, it advances to the next minute of the day to add up all its values.

When the last minute of the day has been processed, the Engine 200 proceeds to Done 714.

FIG. 36 illustrates an exemplary flowchart describing the process for calculating channel viewing metrics by the House Demographic Measurement Engine 200, according to one embodiment. The process begins with Calculate Channel Metrics 760. This routine is called once for each Demographic Code. The Engine 200 then proceeds to Calculate Aggregate Viewing for Each Channel for Entire Day 764. The objective of this routine is to summarize, for each channel, the channel one-minute level data (Ref FIG. 15 field AGGR-CHAN-VIEW-SEC-THIS-MINUTE 3280) across to produce the total viewing seconds for the channel for the entire day (Ref FIG. 15 AGG-CHANNEL-VIEWING-SECONDS 3275).

Once inside this routine, the outer loop goes down the channels, the inner loop goes across the minutes of the day. As the Engine 200 goes down the Channels (Ref FIG. 15 CHAN-VD-CHANNEL-CALL-SIGN-TRGT 3230), it is adding up the aggregate viewing seconds from each channel+minute (Ref FIG. 15 AGGR-CHAN-VIEW-SEC-THIS-MINUTE 3280). The result is being saved in the Channel level aggregate viewing seconds (Ref FIG. 15 AGG-CHANNEL-VIEWING-SECONDS 3275). When the Engine 200 completes adding up all the viewing seconds across the day for one channel, it advances to the next channel to add up all its values.

When the last minute of the day has been processed, the Engine 200 proceeds to Done 766.

FIG. 37 illustrates an exemplary flowchart describing the process for calculating aggregate viewing for each channel for each thirty-minute segment of the day by the House Demographic Measurement Engine 200, according to one embodiment. The process begins with Calculate Channel Viewing for Thirty Minute Segment 740. The Engine 200 then proceeds to Calculate Aggregate Viewing for Each Channel For Each Thirty Minute Segment for Day 742. This routine is called once for each Demographic Code. The objective of this routine is to summarize the channel one-minute level data (Ref FIG. 15 field AGGR-CHAN-VIEW-SEC-THIS-MINUTE 3280) to channel thirty-minute data (Ref FIG. 15 AGG-CHAN-VIEW-SEC-THIS-30-MIN 3295).

Once inside the main process (742), the outer loop goes down the channels, the inner loop goes across the minutes of the day. As the Engine 200 goes across the minutes of the day, it is taking each block of 30 minutes and summarizing all of the one-minute channel level viewing activity during each of the 30 minutes in that thirty-minute segment of the day. The summarized value is recorded in the Aggregate Channel Viewing during that 30 minute segment (Ref FIG. 15 AGG-CHAN-VIEW-SEC-THIS-30-MIN 3295). When it is the first minute of the thirty minute segment, the Engine 200 will copy the Channel Viewing for the first second of that minute 3282 to the first second of the thirty minute segment 3297. When it is minute fifteen of the thirty minute segment, the Engine 200 will copy the Channel Viewing for the first second of that minute 3282 to the first second of minute 15 of the thirty minute segment 3299.

This is repeated for all the channels and for the 48 thirty-minute segments of the day.

When the Engine 200 completes adding up all the viewing seconds for one channel, it advances to the next thirty-minute segment of the day to add up all its values. Reference program code routine V240-AGGR-CHN-VW-SEC-THS-30MIN.

FIG. 38 illustrates an exemplary flowchart describing the process for calculating aggregate viewing across all channels for each thirty-minute segment of the day by the House Demographic Measurement Engine 200, according to one embodiment. The process begins with Calculate Aggregate Viewing for Thirty Minute Segment 744. This routine is called once for each Demographic Code. The objective of this routine is to Calculate Aggregate Viewing During Each thirty-minute segment of the day.

Once inside main process (746), the outer loop goes across the thirty-minute segment of the day, the inner loop goes down the channels. As the Engine 200 goes down the Channels (Ref FIG. 15 CHAN-VD-CHANNEL-CALL-SIGN-TRGT 3230), it is adding up the aggregate viewing seconds from each channel+thirty-minute segment of the day (Ref FIG. 15 AGG-CHAN-VIEW-SEC-THIS-30-MIN 3295). The result is being saved in the Thirty Minute level aggregate viewing seconds (Ref FIG. 16 S30-AGGR-VIEWING-SECONDS 3435). When the Engine 200 completes adding up all the viewing seconds from the various channels for one thirty minute segment, it advances to the next thirty-minute segment of the day to add up all the values for the channels for the thirty minute segment.

This is repeated for all the thirty-minute segments of the day and then for each channel therein. When the last thirty-minute segment of the day has been processed, the process is done. Reference program code routine V240-AGGR-CHN-VW-SEC-THS-30MIN.

FIG. 39 illustrates an exemplary flowchart describing the process for calculating aggregate viewing for each channel for each sixty-minute segment of the day by the House Demographic Measurement Engine 200, according to one embodiment. The process begins with Calculate Channel Viewing for Sixty Minute Segment 760. This routine is called once for each Demographic Code. The Engine 200 then proceeds to Calculate Aggregate Viewing for Each Channel For Each Sixty Minute Segment for Day 762. The objective of this routine is to summarize the channel one-minute level data (Ref FIG. 15 field AGGR-CHAN-VIEW-SEC-THIS-MINUTE 3280) to channel sixty-minute data (Ref FIG. 15 AGG-CHAN-VIEW-SEC-THIS-60-MIN 3300).

Once inside main process (762), the outer loop goes down the channels, the inner loop goes across the minutes of the day. As the Engine 200 goes across the minutes of the day, it is taking each block of 60 minutes and summarizing all of the one-minute channel level viewing activity during each of the 60 minutes in that sixty-minute segment of the day. The summarized value is recorded in the Aggregate Channel Viewing during that 60 minute segment (Ref FIG. 15 AGG-CHAN-VIEW-SEC-THIS-60-MIN 3300). When it is the first minute of the sixty minute segment, the Engine 200 will copy the Channel Viewing for the first second of that minute 3282 to the first second of the sixty minute segment 3302. When it is minute thirty of the sixty minute segment, the Engine 200 will copy the Channel Viewing for the first second of that minute 3282 to the first second of minute 30 of the sixty minute segment 3304. This is repeated for all the channels and for the 24 sixty-minute segments of the day.

When the Engine 200 completes adding up all the viewing seconds for one channel, it advances to the next sixty-minute segment of the day to add up all its values. Reference program code routine V270-AGGR-VIEWING-SECONDS-30M.

FIG. 40 illustrates an exemplary flowchart describing the process for calculating aggregate viewing across all channels for each sixty-minute segment of the day by the House Demographic Measurement Engine 200, according to one embodiment. The process begins with Calculate Aggregate Viewing for Sixty Minute Segment 764. This routine is called once for each Demographic Code. The objective of this routine is to Calculate Aggregate Viewing During Each sixty-minute segment of the day.

Once inside main process (766), the outer loop goes across the sixty-minute segment of the day, the inner loop goes down the channels. As the Engine 200 goes down the Channels (Ref FIG. 15 CHAN-VD-CHANNEL-CALL-SIGN-TRGT 3230), it is adding up the aggregate viewing seconds from each channel+Sixty-minute segment of the day (Ref FIG. 15 AGG-CHAN-VIEW-SEC-THIS-60-MIN 3300). The result is being saved in the Sixty Minute level aggregate viewing seconds (Ref FIG. 16 S60-AGGR-VIEWING-SECONDS 3440). When the Engine 200 completes adding up all the viewing seconds from the various channels for one sixty minute segment, it advances to the next sixty-minute segment of the day to add up all the values for the channels for the sixty minute segment.

This is repeated for all the sixty-minute segments of the day and then for each channel therein. When the last sixty-minute segment of the day has been processed, the process is done. Reference program code routine V270-AGGR-VIEWING-SECONDS-60.

CONCLUSIONS, RAMIFICATIONS, AND SCOPE

In my previous Applications, I have identified numerous Conclusions, Ramifications, and Scope items. Many of those are similar for this application. The Conclusions, Ramifications, and Scope items from (1) my application U.S. application Ser. No. 12/981,301 filed on Dec. 29, 2010, and (2) my U.S. application Ser. No. 13/052,026 filed on Mar. 18, 2011, and (3) my U.S. application Ser. No. 13/360,704 filed on Jan. 28, 2012, and (4) my U.S. application Ser. No. 13/567,073 filed on Aug. 5, 2012 are included herein by reference but not admitted to be prior art.

In this discussion below, I will focus on new ramifications introduced by this application.

From the description above, a number of advantages of some embodiments of my House Demographic Measurement Engine 200 and its supporting processes become evident:

In this specification I have taught how to measure video asset viewing activity at a house level. This provides the information needed to determine house reach which is very important to advertisers. By measuring at a house level, the Engine 200 is eliminating duplicate viewing within the house as would happen when two or more devices in the house are tuned to the same channel at the same time. If an advertiser is paying for Reach, then it would be important to that advertiser to eliminate such duplicate viewing in the house.

Additionally, I have taught how to create one minute, thirty minute and sixty minute aggregations. These are very useful for a variety of downstream analytical work. As a nonlimiting example, the thirty and sixty minute aggregations are very useful in analyzing television program viewing which often has such a length. The format of the aggregated data is convenient for loading to a database or other persisted data store for additional analysis.

Additionally, I have taught how to create these measurements at a demographic group level. This is very useful for a variety of downstream analytical work where it is necessary to understand various demographic attributes of the viewing audience. This data can be used to gain deeper insights into demographics such as age, income, occupation, etc. of the viewers of various programs. These measures can also provide valuable insight into viewer behavior.

The ability to produce metrics that were not previously possible will provide information that is valuable to advertisers and content providers and service providers.

This method of tracking viewing activity on a second-by-second basis is contrary to the teaching of those who work with start time and duration (seconds viewed) in a relational data base model. Thus I am able to solve problems previously found insolvable when limited to using the existing techniques. I am able to provide metrics that could not be produced using existing techniques.

Subsequent Usage of the Metrics

As I have taught, the metrics produced by the Measurement Engine 200 can be loaded to a data warehouse to support additional longitudinal analysis beyond what is done by the Engine. Thus we can readily envision a myriad of uses for the metrics produced by the Measurement Engine 200, several of which I have described in detail.

All of this could be done using anonymous and/or de-identified identifiers for video viewing device, for household, and for viewer all to protect viewer privacy.

Numerous additional metrics can readily be identified by those skilled in the art. Additionally, numerous additional uses for the metrics identified herein will be readily evident to those skilled in the art.

SUMMARY

In accordance with one embodiment, I have disclosed a computer-implemented method of using video viewer interaction data as input to a measurement engine which then calculates: demographic level and aggregate level (a) household reach for advertisements and video content based on user defined reach periods, (b) One-minute, Thirty-minute, and Sixty-minute channel viewing metrics, and (c) One-minute, Thirty-minute, and Sixty-minute aggregate viewing metrics, all based on second-by-second household level viewing activity. My teaching also shows creation of Commercial Schedule Cumulative Audience, Impressions for Reach Periods, Demographic Group Impressions, Average Audience, Average Audience Share, Average Rating, Households Using Television, and Households Using Television Percent using household level data. My design works with IP and linear video delivery. Together these metrics provide detailed information on customer viewing behavior which can be used to drive business decisions for service providers, advertisers, and content producers.

These viewing metrics meet pressing needs for detailed audience viewership information that is not presently available and thus the metrics will be of great value to the industry.

The method of claim 62, wherein determining the video-viewing-activity metric comprises: determining, that each record in a subset of the third plurality of records corresponds to one or more other records in the third plurality of records; and determining, based on a difference between the quantity of records in the third plurality of records and a quantity of records in the subset, the video-viewing-activity metric.
 64. The method of claim 63, wherein determining that each record in the subset of the third plurality of records corresponds to the one or more other records in the third plurality of records comprises: determining that each record in the subset of the third plurality of records is associated with the first video-asset-viewing device; determining that the one or more other records in the third plurality of records are associated with the second video-asset-viewing device; and determining that each record in the subset of the third plurality of records and the one or more other records are associated with a common portion of the plurality of portions of the same time duration.
 65. The method of claim 33, further comprising: determining, by the computing system, at least two of the plurality of intervals that form a second continuous period of time and records of the first plurality of records that correspond to the at least two of the plurality of intervals; and aggregating, by the computing system, the records of the first plurality of records that correspond to the at least two of the plurality of intervals into a fourth plurality of records associated with the video asset.
 66. (canceled)
 67. The method of claim 33, wherein the determination that the second video-asset-viewing device is associated with the first video-asset-viewing device is based on a common identifier associated with the second video-asset-viewing device and the first video-asset-viewing device.
 68. The method of claim 33, wherein the one or more records of the second plurality of records corresponds to one or more duplicative records of the first plurality of records.
 69. The method of claim 33, wherein the determination that the second video-asset-viewing device is associated with the first video-asset-viewing device comprises a determination that a geographical location of the second video-asset-viewing device corresponds to a geographical location of the first video-asset-viewing device.
 70. The method of claim 33, wherein the third plurality of records indicates, for each record of the third plurality of records, a number of video-asset-viewing devices displaying at least a portion of the video asset during an interval corresponding to the record of the third plurality of records.
 71. The method of claim 33, further comprising: receiving, by the computing system, from the first video-asset-viewing device, and via a communication network, data representing video-viewing-activity of the first video-asset-viewing device, wherein generating the first plurality of records comprises generating, based on the data representing video-viewing-activity of the first video-asset-viewing device, the first plurality of records.
 72. The method of claim 71, further comprising: receiving, by the computing system, from the second video-asset-viewing device, and via the communication network, data representing video-viewing-activity of the second video-asset-viewing device, wherein generating the second plurality of records comprises generating, based on the data representing video-viewing-activity of the second video-asset-viewing device, the second plurality of records.
 73. The method of claim 33, wherein determining the reduced plurality of records is based on receiving an input parameter indicating removal of duplicate records.
 74. The method of claim 43, wherein the determination that the second video-asset-viewing device is associated with the first video-asset-viewing device is based on a common identifier associated with the second video-asset-viewing device and the first video-asset-viewing device.
 75. The method of claim 47, wherein the one or more records of the second plurality of records corresponds to one or more duplicative records of the first plurality of records.
 76. The method of claim 51, wherein the determination that the second video-asset-viewing device is associated with the first video-asset-viewing device comprises a determination that a geographical location of the second video-asset-viewing device corresponds to a geographical location of the first video-asset-viewing device.
